CTICasesRib Hemangioma
Imaging findings
CT shows a localized, expansile, sclerotic lesion with prominent trabeculated bone formation and minor soft tissue components arising from the posterolateral aspect of a rib. On PET/CT, the lesion is non-FDG-avid, showing activity similar to normal bone.
Key takeaways
Benign intraosseous hemangiomas of the rib can present as expansile, trabeculated, and sclerotic bone lesions on CT. These lesions can mimic aggressive primary bone neoplasms such as osteosarcoma or chondrosarcoma; however, their benign nature is typically supported by lack of FDG avidity on PET/CT and characteristic histopathological findings.
