Epiphyseal Hemangioma of the Humeral Head: Imaging Findings and Literature Review.

We describe a case of an epiphyseal hemangioma in the humeral head of a 20-year-old man. On plain radiographs, the lesion showed no gross abnormality. The computed tomography images demonstrated the presence of an irregular and lobulating osteolytic lesion with a peripheral sclerotic rim and focal cortical defects. The magnetic resonance images showed an ill-defined low signal intensity on T1-weighted images and mixed low and high signal intensities on T2-weighted images. Additionally, ill-defined marrow enhancement with inner low signal lines was noted in this lesion. The patient was treated with curettage and a bone chip graft. The present case is instructive in the differential diagnosis of epiphyseal bone tumors; furthermore, the possibility of an intraosseous hemangioma should also be considered. [ABSTRACT FROM AUTHOR]
