Many lesions can be located in both or move from the metaphysis to the diaphysis during growth. 2016;207(2):362-8. More heterogenous and irregular with bony trabecular destruction and possible extension beyond the confines of the cortex. Symptoms are usually absent, however, in adult patients with a chondroid lesion in a long bone, particularly of larger size, always consider low-grade chondrosarcoma. (2007) ISBN:0781765188. Enchondromas aswell as low-grade chondrosarcomas are frequently encountered as coincidental findings in patients who have a MRI or bone scan for other reasons. It can also be proven histologically. The X-ray features were divided into two groups according to typical and atypical skeletal lesions. Common: Metastases, multiple myeloma, multiple enchondromas. Hall F & Gore S. Osteosclerotic Myeloma Variants. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. These are inert filled-in non-ossifying fibromas. Here an illustration of the most common sclerotic bone tumors. Chang C, Garner H, Ahlawat S et al. This feature differentiates it from a juxtacortical tumor. The evaluation of a solitary bony lesion in the spine may be more challenging and will often require additional diagnostic testing if benign imaging features are not present on MRI. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Interventional Radiology). 2020;60(Suppl 1):1-16. Wayne State University, Orthopaedic Surgery, MI, 2007 University of Texas Southwestern Medical School, Surgery, TX, 2002 W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. In the epiphysis we use the term avascular necrosis and not bone infarction. Multiple myeloma is a hematologic malignancy of plasma cells that causes bone-destructive lesions and associated skeletal-related events (SREs). Should be included in the differential diagnosis of young patient with multiple lucent lesions (Langerhans cell histiocytosis). 6. Fundamentals of diagnostic radiology. 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. 1. Check for errors and try again. Typical bone metastases are osteolytic (87.5%), with medullary origin (91.6%), and they cannot be distinguished from other osteolytic metastases on the basis of imaging criteria alone. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. Finally, we conclude with a case of an incidentally presenting sclerotic vertebral body lesion.

Skeletal Radiol. Polyostotic lesions > 30 years Fibro-osseous lesion like fibrous dysplasia. However, not all epidermal inclusion cysts involve bone, and some are confined to the subcutaneous tissues. MRI of the sacrum: axial T1-weighted (T1w; Fig. (B) In another patient, a 21-year-old woman, note a radiolucent lesion with sclerotic border affecting the medial cortex of the distal femur ( arrows ). 33.1b), CT scan axial images (c), and bone scintigraphy (d). Here an incidental finding of several eccentric sclerotic lesions of the distal femur. Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. A sclerotic lesion is an unusual hardening or thickening of your bone. Click here for more examples of enchondromas. Once we have decided whether a bone lesion is sclerotic or osteolytic and whether it has a well-defined or ill-defined margins, the next question should be: how old is the patient? Osteoblastic bone metastases are characterized by increased bone formation 2. Ask the patient or the clinician about this. Here two other lesions in different patients that proved to be chondrosarcoma. Differential Diagnosis in Orthopaedic Oncology. Brant WE, Helms CA. Osteosarcoma, chondrosarcoma, and Ewing's sarcoma are the most common types of bone cancer. On CT sclerotic bone metastases typically present as hyperdense lesions, but display a lower density than bone islands 5. Here, we showed that sBT values are higher in patients presenting 496 with bone loss . Sclerotic bone lesions appear exclusively in middle aged black patients. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . giant cell tumor, metastasis, and myeloma; (3) sclerotic . Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. Parosteal osteosarcoma is a sarcoma that has it's origin on the surface of the bone. Well, generally, it means that it is due to a fairly slow-growing process. Purpose: To determine if sclerotic bone lesions evident at body computed tomography (CT) are of value as a diagnostic criterion of tuberous sclerosis complex (TSC) and in the differentiation of TSC with lymphangioleiomyomatosis (LAM) from sporadic LAM. Geode or subchondral cyst in the navicular bone, Geode or subchondral cyst in the tarsal bone, X-ray and MRI of a chondroblasoma in the tarsal bone, Chondromyxoid fibroma (CMF) in the calcaneus. Bone islands demonstrate uniformly low Sclerosis is present from either tumor new bone formation or reactive sclerosis. A cold bone scan is helpful in distinguishing the bone island from a sclerotic metastasis, whereas a warm bone scan is nondiagnostic. Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. Check for errors and try again. An aggressive type is seen in malignant tumors, but also in benign lesions with aggressive behavior, such as infections and eosinophilic granuloma. Diffuse bony sclerosis (mnemonic) Last revised by Joshua Yap on 28 Jun 2022 Edit article Citation, DOI & article data A mnemonic for remembering the causes of diffuse bony sclerosis is: 3 M's PROOF Mnemonic 3 M's PROOF M: malignancy metastases ( osteoblastic metastases) lymphoma leukemia M: myelofibrosis M: mastocytosis S: sickle cell disease Park S, Lee I, Cho K et al. Lumbar CT-HU has the highest pooled correlation (r 2 =0.6) with both spine DEXA and lowest skeletal t-score followed by lumbar CT-HU with hip DEXA (r 2 =0.5) and lumbar MRI with hip (r 2 =0.44) and spine (r 2 =0.41) DEXA. Mixed lytic and sclerotic bone metastases are characterized by the presence of both components, that is areas of bone destruction and areas of increased bone formation within one metastatic tumor deposit or one primary tumor that features both kinds of bone metastases, namely osteolytic and osteoblastic metastases 1. Here a patient with a broad-based osteochondroma. The use of radiological imaging in medical care dates back to 1895 when Radiographs typically show a geographic lytic or ground glass lesion with a well-defined, often extensively sclerotic margin, indicating its indolent nature. Notice that there are small areas of ill-defined osteolysis. The radiographic appearance and location are typical.

Osteopetrosis and pyknodysostosis are likewise hard to mistake for other entities since the bones are denser than in any other disorder, and the long bones tend to have very tiny medullary canals. In the cases in which the solitary sclerotic lesion has increased, uptake on bone scan, follow-up CT, or plain film imaging is recommended at 3-, 6-, and 12-month intervals. Gulati V, Chalian M, Yi J, Thakur U, Chhabra A. Sclerotic Bone Lesions Caused by Non-Infectious and Non-Neoplastic Diseases: A Review of the Imaging and Clinicopathologic Findings. Sarcoidosis is a multi-system disease with a range of . Infection is seen in all ages. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. Typically presents as a lytic lesion in a flat bone, vertebra or diaphysis of long bone. O'Sullivan G, Carty F, Cronin C. Imaging of Bone Metastasis: An Update. DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. Mnemonic for multiple oseolytic lesions: FEEMHI: Sclerotic bone metastases can arise from several different primary malignancies including 1-3: mucinous adenocarcinoma of the gastrointestinal tract (e.g. Particularly chronic osteomyelitis may have a sclerotic appearance. Finally other clues need to be considered, such as a lesion's localization within the skeleton and within the bone, any periosteal reaction, cortical destruction, matrix calcifications, etc. How should one approach sclerotic bone disease? Gadolinium is usually minimal or absent (see right image). in Ewing's sarcoma or lymphoma. BallooningBallooning is a special type of cortical destruction.In ballooning the destruction of endosteal cortical bone and the addition of new bone on the outside occur at the same rate, resulting in expansion. Growth of osteochondromas at adult ages, which is characterized by a thick cartilaginous cap (high SI on T2WI) should raise the suspicion of progression to a peripheral chondrosarcoma. Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation. Click here for more detailed information about fibrous dysplasia. 3, Increased uptake on bone scan associated with a solitary sclerotic lesion is atypical and therefore more worrisome, but largely unhelpful as there are many reports of bone islands having increased Tc-99 m hydroxydiphosphonate (HDP) uptake. The differential diagnosis of bone lesions that result in bony sclerosis will be given. Here a patient with a broad-based osteochondroma with extension of the cortical bone into the stalk of the lesion. If the osteonecrosis is located in the epiphysis, the term avascular osteonecrosis is used. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. Hyperdense oval-shaped lesions with spiculated or paintbrush margins, without distortion of the adjacent bony trabeculae. 105-118. Growth has been demonstrated well after skeletal maturity. 1, The classic bone island has a spiculated or paintbrush border and is much denser on CT than a osteoblastic metastasis. The images show on the left a typical osteolytic NOF with a sharp sclerotic border. A periosteal reaction with or without layering may be present. Case 2: sclerotic metastases from prostate cancer, Generalised increased bone density (mnemonic). Click here for more examples of eosinophilic granuloma. ADVERTISEMENT: Supporters see fewer/no ads. Uncommonly it can be difficult to differentiate a stress fracture from a bone tumor like an osteoid osteoma or from a pathologic fracture, that occurs at the site of a bone tumor. 1. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. Typical presentation: well-defined osteolytic lesion in tarsal bone, patella or epiphysis of a long bone in a 20-year old with pain and swelling in a joint. At Henry Ford Orthopaedics in Chelsea our mission is to provide personalized treatment plans specific to each patient, to ensure the best possible outcome. Frequently encountered as a coincidental finding and can be found in any bone. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Diagnostic brain imaging tests can assess bone fractures, structural problems, blood vessel abnormalities, and changes in brain metabolism. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? The image shows a calcified lesion in the proximal tibia without suspicious features. Lippincott Williams & Wilkins. Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common. Hereditary sclerosing bone dysplasias result from some disturbance in the pathways involved in osteoblast or osteoclast regulation, leading to abnormal accumulation of bone. Amsterdam: Elsevier, 1993. AJR Am J Roentgenol. (A) Small radiolucent lesion exhibiting a thin sclerotic border (arrow) is present in the lateral cortex of the distal tibia of a 13-year-old boy. RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Secondary bone cancer is much more common than primary bone . The juxtacortical mass has a high SI and lobulated contours. WSI digital slide: https://kikoxp.com/posts/4606. ( A1,A2) Transversal CT of the skull of a TSC patient and . Centrally there is an ill-defined osteolytic area. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. Regarding bone disease in SM, increased sBT levels have been 493 associated with both bone sclerosis (due to unknown mechanisms) (8, 18, 19) and 494 osteoporosis (it has been hypothesized that tryptase could induce the production of 495 OPG (61)) (4, 17). Multiple enchondromas are seen in Morbus Ollier. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. The mnemonic I VINDICATE is a commonly used mnemonic for the differential diagnostis of any radiological lesion. sclerosing osteomyelitis of Garr, aggressive features might require an oncological referral and/or biopsy 1, history of malignancy will almost always require additional imaging, follow-up or oncologic referral, high CT attenuation values might help in the differentiation of bone island from osteoblastic metastases 5 but attenuation values should not be used exclusively for the assessment of sclerotic bone lesions 6, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Rapid growth of the mineralized mass is not uncommon. A lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. T2-weighted MR image reveals a lobulated mass with high signal intensity. This is consistent with the diagnosis of a reactive process like myositis ossificans. The radiological report should include a description of the following 2: location and size including the whole extent of disease load, pain attributable to the lesion (if known), Treatment of bone metastases, in general, is usually planned by a multidisciplinary team 10. Moreover, questions such as the . brae in keeping with diffuse bone infarcts. Click here for more examples of chondrosarcoma. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-8429. (2005) ISBN: 9780721602707 -. Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. Radiographic or CT features that suggest malignancy: Use MRI with water-sensitive sequence (T2 FS) to determine cartilage cap thickness. However, cancers that metastasize to bone are very common. Bone islands can be large at presentation. Axial imaging for differentiation from Brodie abscess, osteoblastoma, stress fracture. Sclerotic bone metastasis as initial manifestation of lung adenocarcinoma in a patient with SLE - The Lancet Oncology Clinical Picture | Volume 24, ISSUE 3, e144, March 2023 Sclerotic bone metastasis as initial manifestation of lung adenocarcinoma in a patient with SLE Prof Ruchi Mittal, MD Debashis Maikap, MD Pallavi Mishra, MD Kimura T. Multidisciplinary Approach for Bone Metastasis: A Review. (2007) ISBN:0781765188. 2021;13(22):5711. The differential diagnosis of bone lesions that result in bony sclerosis will be given. PET features high sensitivity in the detection of bone metastases especially 18 NaF-PET is suitable for the detection of sclerotic metastases since it shows tracer uptake in locations with osteoblastic activity and is more accurate than FDG-PET 3. Growth of osteochondroma in skeletally mature patient, Irregular or indistinct surface of lesions, focal lucent regions in interior of lesions, presence of soft tissue mass with scattered or irregular calcifications. Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. Aggressive periosteal reaction Malignant transformation General Considerations Amsterdam: Elsevier; 1993. However, a specific density range has not been specified for those terms 1. There is a metastasis, which presents as a subtle sclerotic lesion in the humerus metaphysis. A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . In patients In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered On the left three bone lesions with a narrow zone of transition. Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. Systematic Approach of Sclerotic Bone Lesions Basis on Imaging Findings. mutation, and both sclerotic and lytic bone lesions together for the first time. Increased uptake on bone scan has been reported in bone islands, especially giant ones, but warrants imaging follow-up. There are a number of other helpful findings you can look for that can help you to cone in on or away from specific entities in one of these differential lists. Impact of Sclerotic. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. Top five location of bone tumors in alphabethic order: Aneurysmal Bone Cyst -tibia, femur, fibula, spine, humerusAdamantinoma -tibia shaft, mandibleChondroblastoma -femur, humerus, tibia, tarsal bone (calc), patellaChondromyxoid fibroma - tibia, femur, tarsal bone, phalanx foot, fibulaChondrosarcoma - femur, rib, iliac bone, humerus, tibiaChordoma -sacrococcygeal, spheno-occipital, cervical, lumbar, thoracicEosinophilic Granuloma -femur, skull, iliac bone, rib, vertebraEnchondroma -phalanges of hands and feet, femur, humerus, metacarpals, ribEwing's sarcoma - femur, iliac bone, fibula, rib, tibiaFibrous dysplasia - femur, tibia, rib, skull, humerusGiant Cell Tumor - femur, tibia, fibula, humerus, distal radiusHemangioma - spine, ribs, craniofacial bones, femur, tibiaLymphoma - femur, tibia, humerus, iliac bone, vertebraMetastases - vertebrae, ribs, pelvis, femur, humerusNon Ossifying Fibroma - tibia, femur, fibula, humerusOsteoid osteoma - femur, tibia, spine, tarsal bone, phalanxOsteoblastoma - spine, tarsal bone (calc), femur, tibia, humerusOsteochondroma - femur, humerus, tibia, fibula, pelvisOsteomyelitis - femur, tibia, humerus, fibula, radiusOsteosarcoma -femur, tibia, humerus, fibula, iliac boneSolitary Bone Cyst -proximal humerus, proximal femur, calcaneal bone, iliac bone. Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. The contour of the involved bone is usually normal or with mild expansive remodelling. Causes: corticosteroid use, sickle cell disease, trauma, Gaucher's disease, renal transplantation. This proved to be a reactive calcification secondary to trauma. As part of the test, a healthcare professional takes a sample of the CSF DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. Check for errors and try again. None of the patients had undergone prior treatment for the metastases. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) 2017;11(1):321. In juxta-articular localisation, the reactive sclerosis may be absent. {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Knipe H, Weerakkody Y, et al. However, a specific density range has not been specified for those terms 1. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. Logistic regression analyses were used to assess the association of joint form and lesions on imaging for axSpA patients and controls. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. 5. Bone and Joint Imaging. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . Coronal T1W image shows lobulated margins and peripheral low SI due to the calcifications. Non-ossifying fibroma which has been filled in. Oncol Rev. T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. Hallmark of osteosarcoma is the production of bony matrix, which is reflected by the sclerosis seen on the radiograph. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. CT It is true that the usual appearance of skeletal metastases is that of focal lesions diffuse sclerosis occurs in only a small fraction of cases of skeletal metastases. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. AJR 1995;164:573-580, Online teaching by the Musculoskeletal Radiology academic section of the University of Washington, by Theodore Miller March 2008 Radiology, 246, 662-674, by Laura M. Fayad, Satomi Kawamoto, Ihab R. Kamel, David A. Bluemke, John Eng, Frank J. Frassica and Elliot K. Fishman. CT-HU has stronger correlations with DEXA than MRI measurements. 2022;51(9):1743-64. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. Spinal lesions are commonly spotted on imaging tests. The mean and maximum attenuation were measured in Hounsfield units. In skeletally mature patients, GCTs begin in the metaphysics and extend deep to the subchondral bone plate of the articular surface. Classic ground glass appearance of the bone. Ulano A, Bredella M, Burke P et al. This is an example of progression of an osteochondroma to a peripheral chondrosarcoma. Home. Matching the degradation rate of the materials with neo bone formation remains a challenge for bone-repairing materials. This is extremely common in Pagets disease but extremely uncommon with a blastic metastasis. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. 2019;290(1):146-54. 2015;7(8):202-11. There is reactive sclerosis with a nidus that is barely visible on the radiograph (blue arrow), but clearly visible on the CT (red arrows). Unable to process the form. There are two patterns of periosteal reaction: a benign and an aggressive type. 3. 1989. In an older patient one should first consider an osteoblastic metastasis. Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . 2003;415(415 Suppl):S4-13. The differential diagnosis of solitary sclerotic bone lesions can be narrowed down according to the following factors 1-3: cartilaginous matrix (rings and arcs appearance). Some prefer to divide patients into two age groups: 30 years. Most cases of chronic osteomyelitis look pretty nonspecific. Subungual exostoses are bony projections which arise from the dorsal surface of the distal phalanx, most commonly of the hallux. Here a 44-year old male with a mixed lytic and sclerotic mass arising from the fifth metacarpal bone. The diagnosis was fibrous dysplasia. Melorrheostosis is a dysplasia of the bone, characterized by apposition of mature bone on the outer or inner surface of cortical bone. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Notice the homogeneous thickening of the cortical bone. Metastases and multiple myelomaIn patients > 40 years metastases and multiple myeloma are the most common bone tumors.Metastases under the age of 40 are extremely rare, unless a patient is known to have a primary malignancy.Metastases could be included in the differential diagnosis if a younger patient is known to have a malignancy, such as neuroblastoma, rhabdomyosarcoma or retinoblastoma. Bone marrow edema can happen with fractures and other serious bone or joint injuries. Sclerosis can also be reactive, e.g. Brant WE, Helms CA. Sclerotic bone lesions at abdominal magnetic resonance imaging in children with tuberous sclerosis complex. The differential diagnosis mostly depends on the age of the patient and the findings on the conventional radiographs. Here a lesion located in the epi- and metaphysis of the proximal humerus. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. Generic Differential Diagnosis of Sclerotic Bone Lesions. Diffuse skeletal infarcts can be a common cause of diffuse skeletal sclerosis. Uncommonly it can be difficult to differentiate a stress fracture from a pathologic fracture, that occurs at the site of a bone tumor. Location within the skeleton Radiology. Sometimes a more solid periosteal reaction is present combined with cortical thickening and broadening of the bone. Ewing sarcoma with lamellated and focally interrupted periosteal reaction. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. A surface osteosarcoma could be considered in the differential diagnosis. 2. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. The MR image shows that the lesion has lobulated contours and nodular enhancement. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i The lesion is predominantly calcified. It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. 2 ed. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. J Korean Soc Radiol. 4.
