The most common focal metastatic lesions originate from the breast (37%), lung (15%), kidney (6%), and thyroid (4%) 43. AJR Am J Roentgenol. DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. CT imaging example of the location pattern of sclerotic bone lesions in the skull, spine, and pelvis of TSC patients and control subjects. This shows that differentiating a tumor from a reactive proces scan be quite difficult in some cases. The contour of the involved bone is usually normal or with mild expansive remodelling. 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. These lesions usually regress spontaneously and may then become sclerotic. The image on the right is of a different patient who has an old NOF that shows complete fill in. 4. Here Melorrheostosis of the ulna with the appearance of candle wax. Causes: corticosteroid use, sickle cell disease, trauma, Gaucher's disease, renal transplantation. This is a routine medical imaging report. The differential diagnosis of bone lesions that result in bony sclerosis will be given. Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. 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. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. 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. J Korean Soc Radiol. 1. Starting on day 28, sclerotic changes surrounding the bone absorption area were detected. Endosteal scalloping of the cortical bone can be seen in benign lesions like Fybrous dysplasia and low-grade chondrosarcoma. Both of these entities may have an aggressive growth pattern. Small osteolytic lesion (up to 1.5 cm) with or without central calcification. The differential diagnosis for bone tumors is dependent on the age of the patient, with a very different set of differentials for the pediatric patient. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. Park S, Lee I, Cho K et al. Bone scan shows no high activity, opposed to low-grade intraosseous osteosarcoma. Teaching Point: Metastasis is the most common malignant rib lesion. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . Most commonly encountered bone tumor in the small bones of the hand and foot. 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. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i 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. The location of a bone lesion within the skeleton can be a clue in the differential diagnosis. Ulano A, Bredella M, Burke P et al. Acute osteomyelitis is characterised by osteolysis.

Osteosarcoma (2) Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Infections and eosinophilic granulomaInfections and eosinophilic granuloma are exceptional because they are benign lesions which can mimick a malignant bone tumor due to their aggressive biologic behavior. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. The subchondral bone is key to cartilage and joint health. Semin. (2005) ISBN: 9780721602707 -. Case Report Med. Check for errors and try again. Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. Hall F & Gore S. Osteosclerotic Myeloma Variants. Typical presentation: central lesion in metaphysis or diaphysis with a well defined serpentiginous border. A mnemonicfor remembering the causes of diffuse bony sclerosis is: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. When considering congenital causes of sclerotic lesions, benign causes such as bone islands or osteopoikilosis usually have a fairly typical appearance and are hard to mistake. Bone islands can be large at presentation. The radiographic appearance and location are typical. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. 105-118. Infection is seen in all ages. Fundamentals of Skeletal Radiology, second edition Here a lesion in the epiphysis, which was the result of post-traumatic osteonecrosis. BackgroundCongenital generalized lipodystrophy (CGL) is a rare disease. 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. ( A1,A2) Transversal CT of the skull of a TSC patient and . Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. 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. Breast cancer (usually mixed lytic/sclerotic), Bone islands do not have edema in the adjacent bone marrow or extension into surrounding soft tissue or adjacent bony destruction. . Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. 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. If you can find evidence of subchondral collapse or the typical lucent/sclerotic appearance of the necrotic bone in the weight-bearing bone, then osteonecrosis becomes a much more likely diagnosis. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. About Us; Staff; Camps; Scuba. brae in keeping with diffuse bone infarcts. Here a well-defined mixed sclerotic-lytic lesion of the left iliac bone. It can differentiate predominantly osteoblastic from osteolytic bone metastases 9 as well as easily demonstrate and assess complications such as pathological fractures or spinal cord compression 2,3. In the epiphysis we use the term avascular necrosis and not bone infarction. Strahlenther Onkol. Unable to process the form. 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. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. 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. 12. Small area of lucency with adjacent sclerosis at the distal right medial femoral metaphysis that could relate to enthesopathic change or remodeling of a fibroxanthoma of bone.. AJR 2005; 185:915-924. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. These lesions are not osteochondromas, but consist of reactive cartilage metaplasia.

Radiographs typically show a geographic lytic or ground glass lesion with a well-defined, often extensively sclerotic margin, indicating its indolent nature. If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). An aggressive type is seen in malignant tumors, but also in benign lesions with aggressive behavior, such as infections and eosinophilic granuloma. If the process is slower growing, then the bone may have time to mount an offense and try to form a sclerotic area around the offender. Imaging: ADVERTISEMENT: Supporters see fewer/no ads. Spine (Phila Pa 1976). On the right T2-WI with FS of same patient.. 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. Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding.

Eosinophilic granuloma like osteomyelitis, can be a serious mimicker of malignancy (particularly Ewing sarcoma). In aggressive periostitis the periosteum does not have time to consolidate. Here images of a patient with prostate cancer. In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered These are infections and eosinophilic granuloma. AJR 2000; 175:261-263. Radiological atlas of bone tumours of the Netherlands Committee on Bone Tumors Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 Uncommonly it can be difficult to differentiate a stress fracture from a pathologic fracture, that occurs at the site of a bone tumor. 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. In 8 of the 24 patients, 17 of 52 new sclerotic lesions (33%) had showed positive uptake on previous bone scans. 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. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Radiographic or CT features that suggest malignancy: Use MRI with water-sensitive sequence (T2 FS) to determine cartilage cap thickness. Sclerotic or blastic bone metastases can arise from a number of different primary malignancies including prostate carcinoma (most common), breast carcinoma (may be mixed), transitional cell carcinoma (TCC), carcinoid, medulloblastoma, neuroblastoma, mucinous adenocarcinoma of the gastrointestinal tract (e.g., colon carcinoma, gastric carcinoma), Infection may be well-defined or ill-defined osteolytic, and even sclerotic. It may be spiculated and interrupted - sometimes there is a Codman's triangle. 2. This represents a thick cartilage cap. However, cancers that metastasize to bone are very common. 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 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. For the unexpected bone lesions, the distinguishing anatomic features and a generalized imaging approach will be reviewed for four frequently encountered scenarios: chondroid lesions, sclerotic bone lesions, osteolytic lesions, and areas of focal marrow abnormality. The juxtacortical mass has a high SI and lobulated contours. 2021;13(22):5711. (see diagnostic imaging pearls). A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. Bone flare phenomenon was well described on bone scans; a study 25 revealed the appearance of new or worsening bone sclerosis at 3-month CT assessment in three of 67 castration-resistant prostate cancer (CRPC) patients undergoing systemic treatment. CT-HU has stronger correlations with DEXA than MRI measurements. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration. Fundamentals of diagnostic radiology. 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. 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. It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. A disadvantage of MRI is that the detection is poor in bones with a small marrow cavity such as the ribs and these bones are better investigated with CT 2,3. growth of osteohondroma in skeletally mature patients, irregular or indistinct surface of lesions, soft tissue mass with scattered or irregular calcifications. Donald Resnick, Mark J. Kransdorf. {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Knipe H, Weerakkody Y, et al. Most common malignant bone tumor, which is almost always low-grade, Primary sites of origin: proximal long bones, around knee, pelvis and shoulder girdle, usually central and metaphyseal. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. Differential Diagnosis in Orthopaedic Oncology. found incidentally on the imaging studies. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). Unable to process the form. Click here for more examples of eosinophilic granuloma. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. 7A, and 7B ). Infections, a common tumor mimicker, are seen in any age group. Sclerotic metastases arise from . The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. FD is often purely lytic, but may have a groundglass appearance as the matrix calcifies. A bone island larger than 1 cm is referred to as a giant bone island (12). 2018;10(6):156. Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . Enhancement after i.v. Materials and Methods 5, In the cases with no known primary malignancy that are being followed with serial imaging, if the lesion increases in diameter by greater than 25% at 6 months or less, or greater than 50% at 12 months, open biopsy has been recommended by Brien et al. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Bone islands demonstrate uniformly low Sclerotic bone lesions at abdominal magnetic resonance imaging in children with tuberous sclerosis complex. Particularly chronic osteomyelitis may have a sclerotic appearance. 3. Radiographs are specific but suffer from low sensitivity 1. When you are considering osteonecrosis in your differential diagnosis, look at the joints carefully. Well, generally, it means that it is due to a fairly slow-growing process. Radiologe. Hereditary sclerosing bone dysplasias result from some disturbance in the pathways involved in osteoblast or osteoclast regulation, leading to abnormal accumulation of bone. Notice that many benign osteolytic lesions that are frequently seen in younger age groups may heal and appear as sclerotic lesions in the middle aged group. T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. Recommendation: No specific imaging recommendation. Chang C, Garner H, Ahlawat S et al. 14. Osteoblastic bone metastases are characterized by increased bone formation 2. Axial T1-weighted MR image shows homogeneous low signal intensity due to the compact bone apposition. Diffuse bony sclerosis (mnemonic). Notice that the cortical bone extends into the lesion. In juxta-articular localisation, the reactive sclerosis may be absent. Mixed lytic/sclerotic lesion of right posterolateral 10 th rib, with extensive aggressive-appearing periostitis, as well as a multilobulated soft tissue component. The most reliable indicator in determining whether these lesions are benign or malignant is the zone of transition between the lesion and the adjacent normal bone (1). This part corresponds to a zone of high SI on T2-WI with FS on the right. MRI shows large tumor within the bone and permeative growth through the Haversian channels accompanied by a large soft tissue mass, which is barely visible on the X-ray. Non-ossifying fibroma (NOF) can be encoutered occasionally as a partial or completely sclerotic lesion. All images were evaluated for joint form, erosion, sclerosis, fat metaplasia and bone marrow oedema (BMO) by two independent readers. The use of PET/CT imaging with new radiotracers enables a non-invasive assessment of the presence of the target of treatment in the whole body and provides the possibility to combine functional information with anatomical details.
