2016;207(2):362-8. 3. Recommendation: No specific imaging recommendation. Lesions in the bone are usually identified on radiographic images - chiefly X-rays - but also on CT and MRI scans. There is reactive sclerosis with a nidus that is barely visible on the radiograph (blue arrow), but clearly visible on the CT (red arrows). The radiographic appearance and location are typical. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Presentation: pain, mass, pathologic fracture. Generic Differential Diagnosis of Sclerotic Bone Lesions. Here some typical examples of bone tumors in the spine. 1991;167(9):549-52. Notice the homogeneous thickening of the cortical bone. by Mulder JD et al Common: Metastases, multiple myeloma, multiple enchondromas. Impact of Sclerotic. 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. I think that the best way is to start with a good differential diagnosis for sclerotic bones. Publicationdate 2010-04-10 / update 2022-03-17. General Considerations Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. The epiphysis, metaphysis and diaphysis may be involved. Diffuse bony sclerosis (mnemonic). 7. 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. 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 Degenerative subchondral cyst: epiphyseal, Chondroid matrix in cartilaginous tumors like enchondromas and chondrosarcomsa. Sclerotic bone metastases can arise from several different primary malignancies including 1-3: mucinous adenocarcinoma of the gastrointestinal tract (e.g. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. As part of the test, a healthcare professional takes a sample of the CSF An aggressive type is seen in malignant tumors, but also in benign lesions with aggressive behavior, such as infections and eosinophilic granuloma. In this case, because of the increased uptake on bone scintigraphy, a follow-up MRI was recommended at 6 and 12 months. Hyperdense oval-shaped lesions with spiculated or paintbrush margins, without distortion of the adjacent bony trabeculae. AJR Am J Roentgenol. Less dense on CT and more heterogeneous than bone islands. brae in keeping with diffuse bone infarcts. Here two patients with a bizar parosteal osteochondromatous proliferation (BPOP), also called Nora's lesion. Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. Enchondroma is a fairly common benign cartilaginaous lesion which may present as an entirely lytic lesion without any calcification, as a dense calcified lesion or as a mixed leson with osteolysis and calcifications. and PD-L1 PET/CT (PD-L1 positivity is defined as having at least one lesion with radiotracer uptake over the . {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. Radiology. 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. Click here for more detailed information about NOF. In some cases however the osteolytic nidus can be visible on the radiograph (figure).

Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. Sclerotic bone metastases. It grows primarily into the surrounding soft tissues, but may also infiltrate into the bone marrow. D'Oronzo S, Coleman R, Brown J, Silvestris F. Metastatic Bone Disease: Pathogenesis and Therapeutic Options. Check for errors and try again. Many lesions can be located in both or move from the metaphysis to the diaphysis during growth. AJR Am J Roentgenol. 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.

The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. Rib metastases may be osteolytic, sclerotic, or mixed. Centrally there is an ill-defined osteolytic area. 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. Sclerosing bone dysplasias are skeletal abnormalities of varying severity with a wide range of radiologic, clinical, and genetic features. Mnemonic for multiple oseolytic lesions: FEEMHI: Macedo F, Ladeira K, Pinho F et al. Particularly chronic osteomyelitis may have a sclerotic appearance.

Fayad, Satomi Kawamoto, Ihab R. Kamel, David A. Bluemke, John Eng, Frank J. Frassica and Elliot K. Fishman. 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. Calcifications in chondroid tumors have many descriptions: rings-and-arcs, popcorn, focal stippled or flocculent. giant cell tumor, metastasis, and myeloma; (3) sclerotic . Contrast-enhanced T1-weighted MR image demonstrates heterogeneous enhancement of the mass with extensive surrounding edema. Sclerotic or osteoblastic bone metastases are distant tumor deposits of a primary tumor within bone characterized by new bone deposition or new bone formation. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. Most of the time, sclerotic lesions are benign. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). 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. 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. 33.1b), CT scan axial images (c), and bone scintigraphy (d). RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Differential Diagnosis of Diffuse Sclerotic Bone Lesions. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding. Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Authors Home. The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. Notice that CT depicts these lesions far better (red arrows). This feature differentiates it from a juxtacortical tumor. A lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. Osteoblastic metastases (2) Here Melorrheostosis of the ulna with the appearance of candle wax. Interventional Radiology). 2. Amorphous mineralisation is present in most lesions. Well, generally, it means that it is due to a fairly slow-growing process. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement.

Lippincott Williams & Wilkins. 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? It classically presents with nocturnal pain in young patients, painful scoliosis, and marked relief from NSAIDs (nonsteroidal anti-inflammatory drugs). An ill-defined border with a broad zone of transition is a sign of aggressive growth (1). Unable to process the form. 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. Fibro-osseous lesion like fibrous dysplasia. Azar A, Garner H, Rhodes N, Yarlagadda B, Wessell D. CT Attenuation Values Do Not Reliably Distinguish Benign Sclerotic Lesions From Osteoblastic Metastases in Patients Undergoing Bone Biopsy. SWI:low signal intensity on the inverted magnitude and phase images 9. The signal intensity on MR depends on the amount of calcifications and ossifications and fibrous tissue (low SI) and cystic components (high SI on T2). Sclerotic jaw lesions are not rare and are frequently encountered on radiographs and computed tomography (CT). 10. At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. It can also be proven histologically. Amsterdam: Elsevier; 1993. Journal of Bone Oncology. A periosteal reaction with or without layering may be present. A brain MRI can . Both imaging modalities achieved only a moderate correlation with DEXA. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al. This 'neocortex' can be smooth and uninterrupted, but may also be focally interrupted in more aggressive lesions like GCT. Rapid growth of the mineralized mass is not uncommon. Many important signaling . Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. Here an illustration of the most common sclerotic bone tumors. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. Usually one bone is involved. Amsterdam: Elsevier, 1993. Finally, we conclude with a case of an incidentally presenting sclerotic vertebral body lesion. by Clyde A. Helms In this paper, we review the recent years of literature on deep learning-based multiple-lesion recognition. 6. Sclerotic bone lesions at abdominal magnetic resonance imaging in children with tuberous sclerosis complex. 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). 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 4. Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. 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 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. Small osteolytic lesion (up to 1.5 cm) with or without central calcification. However, a specific density range has not been specified for those terms 1. Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). A bone island larger than 1 cm is referred to as a giant bone island (12). These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. 2017;11(1):321. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) AJR 2000; 175:261-263. Increased uptake on bone scan has been reported in bone islands, especially giant ones, but warrants imaging follow-up. This is consistent with the diagnosis of a reactive process like myositis ossificans. Gadolinium is usually minimal or absent (see right image). 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. Should be included in the differential diagnosis of young patient with multiple lucent lesions (Langerhans cell histiocytosis). Most commonly originate from prostate and breast cancer and less frequently from lung cancer, lymphoma or carcinoid. Large lesions tend to expand into both areas. Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. The mnemonic I VINDICATE is a commonly used mnemonic for the differential diagnostis of any radiological lesion. UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? 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.. 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. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? Brant WE, Helms CA. 2 ed. Sclerosis is present from either tumor new bone formation or reactive sclerosis. Another finding classic for Pagets disease is that it almost always starts at one end of a bone and then spreads toward the other end of the bone. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. Benign periosteal reaction This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). Chrondroid tumors are more frequently encountered than bone infarcts. Focal sclerotic bony lesions (mnemonic). Non-ossifying fibroma which has been filled in. Osteoid matrix in osseus tumors like osteoid osteomas and osteosarcomas. Click here for more examples of chondroblastoma. Brant WE, Helms CA. 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. One study, using a mean attenuation of 885 HU and a maximum attenuation of 1,060 HU as cut-off values, distinguished the higher density bone islands from lower density osteoblastic metastases with 95% sensitivity and 96% specificity. Infection is seen in all ages. (2007) ISBN:0781765188. Ulano A, Bredella M, Burke P et al. 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. 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. by Clyde A. Helms Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). Mild mass effect on adjacent lung, diaphragm, and liver. Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. This shows that differentiating a tumor from a reactive proces scan be quite difficult in some cases. Click here for more examples of enchondromas. Urgency: Routine. Here an example of a patient with a stress fracture of the distal fibula. Cortical destruction (3) FIGURE 2.7 Computed tomography of osteoid osteoma. 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. Parosteal osteosarcoma is a sarcoma that has it's origin on the surface of the bone. In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. Here a well-defined mixed sclerotic-lytic lesion of the left iliac bone. Causes: corticosteroid use, sickle cell disease, trauma, Gaucher's disease, renal transplantation. 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. Isaac A, Dalili D, Dalili D, Weber M. State-Of-The-Art Imaging for Diagnosis of Metastatic Bone Disease. This proved to be a reactive calcification secondary to trauma. The zone of transition is the most reliable indicator in determining whether an osteolytic lesion is benign or malignant (1). MRI of the sacrum: axial T1-weighted (T1w; Fig. Check for errors and try again. Here, we showed that sBT values are higher in patients presenting 496 with bone loss . 33.1a) and sagittal short tau inversion recovery (STIR; Fig. 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. Skeletal Radiol. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Sclerotic metastases arise from . Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. 5 Biopsy should be considered in atypical cases or in high-risk patients with primary malignancies associated with osteoblastic metastatic disease. 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. Click here for more information about bone island. Most bone tumors are solitary lesions. Plain films typically reveal lesions with moth-eaten or permeative pattern of the transition zone with irregular cortical destruction and an interrupted periosteal reaction with soft tissue extension. 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. A benign type of periosteal reaction is a thick, wavy and uniform callus formation resulting from chronic irritation.
