Here an incidental finding of several eccentric sclerotic lesions of the distal femur. (see diagnostic imaging pearls). Oncol Rev. Most cases of chronic osteomyelitis look pretty nonspecific. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. Small zone of transitionA small zone of transition results in a sharp, well-defined border and is a sign of slow growth.A sclerotic border especially indicates poor biological activity. Less common: Fibrous dysplasia, Brown tumors of hyperparathyroidism, bone infarcts. Complete envelopment may occur. However, a specific density range has not been specified for those terms 1. None of the patients had undergone prior treatment for the metastases. The epiphysis, metaphysis and diaphysis may be involved. Fisher C, DiPaola C, Ryken T et al. DD: old SBC. Should be included in the differential diagnosis of young patient with multiple lucent lesions (Langerhans cell histiocytosis). These lesions were possibly misinterpreted as new when applying WHO criteria. Small osteolytic lesion (up to 1.5 cm) with or without central calcification. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. Osteosarcoma (2) Fundamentals of diagnostic radiology. This could very well be an enchondroma. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. Rib metastases may be osteolytic, sclerotic, or mixed. Lesions in the bone are usually identified on radiographic images - chiefly X-rays - but also on CT and MRI scans. Sometimes a more solid periosteal reaction is present combined with cortical thickening and broadening of the bone. A sclerotic lesion is an unusual hardening or thickening of your bone. Concerning the above factors the differential diagnosis includes the following lesions 1-3: sclerotic bone metastasis: might be solitary because no others are present or have been imaged, infection: e.g. The image shows a calcified lesion in the proximal tibia without suspicious features. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. As you can see, by just dropping the items that tend to cause generalized sclerosis, we have generated a fairly good differential for focal lesions. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. These are inert filled-in non-ossifying fibromas. This solitary, uniformly high-density lesion with neither edema in the surrounding bone marrow nor extension into the surrounding soft tissue most likely represents a giant bone island. Most bone tumors are solitary lesions. Enchondromas aswell as low-grade chondrosarcomas are frequently encountered as coincidental findings in patients who have a MRI or bone scan for other reasons. Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . 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. One can then apply various features of the lesions to this differential, and exclude some things, elevate some things, and downgrade others in the differential. Complete destruction may be seen in high-grade malignant lesions, but also in locally aggressive benign lesions like EG and osteomyelitis. In the active phase there is multilaminar periosteal reaction and bone and soft tissue edema. In this case we see the pathognomonic triad of bone expansion, cortical thickening and trabecular bone thickening in the mixed lytic and sclerotic phase of Paget's disease of right hemipelvis. There are calcified strands within the soft tissues. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. The pathogenesis of myeloma-related bone disease (MBD) is the imbalance of the bone-remodeling process, which results from osteoclast activation, osteoblast suppression, and the immunosuppressed bone marrow microenvironment. Diffuse skeletal infarcts can be a common cause of diffuse skeletal sclerosis. The major part of the lesion consists of reactive sclerosis. Wide zone of transition Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3 . O'Sullivan G, Carty F, Cronin C. Imaging of Bone Metastasis: An Update. Classic ground glass appearance of the bone. In this case, because of the increased uptake on bone scintigraphy, a follow-up MRI was recommended at 6 and 12 months. The diagnosis was fibrous dysplasia. Fibro-osseous lesion like fibrous dysplasia. This proved to be a reactive calcification secondary to trauma. Mark Blumenkehl, MD is a specialist in Gastroenterology whose practice locations include: Detroit, Sterling Hgts Skeletal Radiol. Isaac A, Dalili D, Dalili D, Weber M. State-Of-The-Art Imaging for Diagnosis of Metastatic Bone Disease. 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. Here two other lesions in different patients that proved to be chondrosarcoma. Conclusion. Biopsy revealed dedifferentiated chondrosarcoma. I think that the best way is to start with a good differential diagnosis for sclerotic bones. Edema often present in the surrounding bone marrow. 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. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. 7, Behrang Amini, Susana Calle, Octavio Arevalo, Richard M.

Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). Differentiating between a diaphyseal and a metaphyseal location is not always possible. 2022;51(9):1743-64. These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Society of Skeletal Radiology- White Paper. Growth has been demonstrated well after skeletal maturity. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Bone islands demonstrate uniformly low Sclerosing bone dysplasias are skeletal abnormalities of varying severity with a wide range of radiologic, clinical, and genetic features. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. T2-weighted MR image reveals a lobulated mass with high signal intensity. . 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. (2007) ISBN: 9780781779302 -. (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 ). Here a lesion in the epiphysis, which was the result of post-traumatic osteonecrosis. Clin Orthop Relat Res. Diagnostic brain imaging tests can assess bone fractures, structural problems, blood vessel abnormalities, and changes in brain metabolism. J Korean Soc Radiol. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Typically presents as a lytic lesion in a flat bone, vertebra or diaphysis of long bone. Sclerotic or osteoblastic bone metastases are distant tumor deposits of a primary tumor within bone characterized by new bone deposition or new bone formation. They can affect any bone and be either benign (harmless) or malignant (cancerous). A lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. found incidentally on the imaging studies. A mean CT attenuation threshold of 885 HU and a maximum attenuation threshold of 1060 HU has been found supportive in the differentiation of untreated osteoblastic and bone island in one study 7, but the exclusive use of attenuation values for the assessment of sclerotic bone lesions has been discouraged 8. Cartilaginous tumors in particular chondrosarcoma may show endosteal scalloping, while a bone infarct does not. Click here for more detailed information about fibrous dysplasia. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). Bone scintigraphy (99mTc MDP) is very sensitive for the detection of osteoblastic providing information on osteoblastic activity but suffers from specificity with a false-positivity rate ranging up to 40% 1. Sarcoidosis is a multi-system disease with a range of . 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? An aggressive type is seen in malignant tumors, but also in benign lesions with aggressive behavior, such as infections and eosinophilic granuloma. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . Hallmark of osteosarcoma is the production of bony matrix, which is reflected by the sclerosis seen on the radiograph. Notice the numerous predominantly osteoblastic metastases. More uniform cortical bone destruction can be found in benign and low-grade malignant lesions. AJR Am J Roentgenol. Continue with the MR-images. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. Solitary sclerotic bone lesion. Frequently encountered as a coincidental finding and can be found in any bone. This is especially true when the injury involves the spine, hip, knees, or ankle. Infection is seen in all ages. Focal sclerotic bony lesions (mnemonic) Last revised by Daniel J Bell on 18 Feb 2019 Edit article Citation, DOI & article data A popular mnemonic to help remember causes of focal sclerotic bony lesions is: HOME LIFE Mnemonic H: healed non-ossifying fibroma (NOF) O: osteoma M: metastasis E: Ewing sarcoma L: lymphoma I: infection or infarct Metastases are the most common malignant bone tumors. Here a radiograph of the pelvis with a barely visible osteoblastic metastasis in the left iliac bone (blue arrow). DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. 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. They usually affect posterior vertebral elements and their number and size increase with age. This feature differentiates it from a juxtacortical tumor. Cancers (Basel). Bone metastases have a predilection for hematopoietic marrow sites: spine, pelvis, ribs, cranium and proximal long bones: femur, humerus. This part corresponds to a zone of high SI on T2-WI with FS on the right. However, the exact mechanism that leads to osteoblastic formation is not entirely elucidated. . In Section 2, we give the general technical route for classification, detection and segmentation of multiple-lesion.After that, in Section 3, the paper will review the recognition of multiple-lesion in six organ and tissue areas, including brain, eye, skin, breast, lung, and abdomen. Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. 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 In some cases however the osteolytic nidus can be visible on the radiograph (figure). 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. 2. Radiographs typically show a geographic lytic or ground glass lesion with a well-defined, often extensively sclerotic margin, indicating its indolent nature. The lesion shows increased uptake of the tracer in the bone scan (arrow in Fig. 2. Tumor Pathology- Bone Lesion Bone Tumor Osteomyelitis When you identify a bone lesion, follow this basic checklist to help you accurately describe the lesion and narrow your differential diagnosis: Bone Tumors and Tumorlike Conditions: Analysis with Conventional Radiography Theodore T. Miller Radiology 2008 246:3, 662-674 In an older patient one should first consider an osteoblastic metastasis. Click here for more examples of eosinophilic granuloma. 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration. Materials and Methods The mnemonic I VINDICATE is a commonly used mnemonic for the differential diagnostis of any radiological lesion. 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. The benign type is seen in benign lesions such as benign tumors and following trauma. Bone scan shows no high activity, opposed to low-grade intraosseous osteosarcoma. The contour of the involved bone is usually normal or with mild expansive remodelling. Sclerotic bone metastases can arise from several different primary malignancies including 1-3: mucinous adenocarcinoma of the gastrointestinal tract (e.g. This type of periostitis is multilayered, lamellated or demonstrates bone formation perpendicular to the cortical bone. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. A lumbar puncture (LP) is a diagnostic procedure used to obtain a sample of cerebrospinal fluid (CSF) to look for signs of infection or inflammation. 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. Here some typical examples of bone tumors in the spine. Sclerotic bone metastases. Chrondroid tumors are more frequently encountered than bone infarcts. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-8429. Most primary bone tumors are seen in patients In patients > 30 years we must always include metastases and myeloma in the differential diagnosis. Multiple enchondromas are seen in Morbus Ollier. Ulano A, Bredella M, Burke P et al. Mineralization in osteoid tumors can be described as a trabecular ossification pattern in benign bone-forming lesions and as a cloud-like or ill-defined amorphous pattern in osteosarcomas. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. Spinal lesions are commonly spotted on imaging tests. 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. Location within the skeleton Non-ossifying fibroma (NOF) can be encoutered occasionally as a partial or completely sclerotic lesion. Cortical destruction is a common finding, and not very useful in distinguishing between malignant and benign lesions. Wayne State University, Orthopaedic Surgery, MI, 2007 University of Texas Southwestern Medical School, Surgery, TX, 2002 Occasionally slowly enlargement can be seen. Age is the most important clinical clue in differentiating possible bone tumors.There are many ways of splitting age groups, as can be seen in the table, where the morphology of a bone lesion is combined with the age of the patient. Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. Increased uptake on bone scan has been reported in bone islands, especially giant ones, but warrants imaging follow-up. Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation. Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. Osteochondroma is a bony protrusion covered by a cartilaginous cap. The bone scan is also helpful to look for additional sites of increased uptake that may not have been imaged, such as multiple nontraumatic rib, calvarial, or long bone lesions, which would strongly suggest the diagnosis of metastatic disease. The use of radiological imaging in medical care dates back to 1895 when Osteoblastic metastases (2) Stress fractures occur in normal (fatigue fractures) or metabolically weakened (insufficiency fractures) bones. Impact of Sclerotic. This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. A popular mnemonic to help remember causes of focal sclerotic bony lesions is: Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. In 8 of the 24 patients, 17 of 52 new sclerotic lesions (33%) had showed positive uptake on previous bone scans. giant cell tumor, metastasis, and myeloma; (3) sclerotic . Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. 1. If there are multiple or polyostotic lesions, the differential diagnosis must be adjusted. This shows that differentiating a tumor from a reactive proces scan be quite difficult in some cases. Case Report Med. A high grade chondrosarcoma must be considered in the differential diagnosis. Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. Bone islands can be large at presentation. How should one approach sclerotic bone disease? 5 Biopsy should be considered in atypical cases or in high-risk patients with primary malignancies associated with osteoblastic metastatic disease. Usually one bone is involved. Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. Radiographs are specific but suffer from low sensitivity 1. Notice the numerous ill-defined osteoblastic metastases. 2021;216(4):1022-30. DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. Check for errors and try again. Radiographic or CT features that suggest malignancy: Use MRI with water-sensitive sequence (T2 FS) to determine cartilage cap thickness. CT scan is usually very helpful in detecting the nidus and differentiating osteoid osteoma from other sclerotic lesions like osteoblastoma, osteomyelitis, arthritis, stress fracture and enostosis. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity.

Rohrmann, Jr., M.D., Endowment for Radiology Resident Educational Excellence, Michael and Rebecca McGoodwin Endowment for Radiology Resident and Fellow Training and Education, The Norman and Anne Beauchamp Endowed Fund for Radiology. About Us; Staff; Camps; Scuba. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. It classically presents with nocturnal pain in young patients, painful scoliosis, and marked relief from NSAIDs (nonsteroidal anti-inflammatory drugs). 6. Intense uptake on bone scintigraphy as we would expect in high grade chondrosarcoma. Central location most common with some expansion and cortical thinning. Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. A molecular classification has been also proposed. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 2, The primary utility of the bone scan is that if there is no increased uptake, sclerotic metastatic disease is highly unlikely; therefore, the lesion can be considered most likely a bone island and follow-up radiographic imaging obtained. Here an image of a patient with chronic osteomyelitis. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. Radiologe. Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. Adamantinoma in case of a sclerotic lesion with several lucencies of the tibia in a young patient. The sagittal T1WI and Gd-enhanced T1W-image with fatsat show a large tumor mass infiltrating a large portion of the distal femur and extending through the cortex into the soft tissues. This is consistent with the diagnosis of a reactive process like myositis ossificans. Radiologic Atlas of Bone Tumors Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-10490, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":10490,"questionManager":null,"mcqUrl":"https://radiopaedia.org/articles/sclerotic-bone-metastases/questions/1747?lang=us"}.
