[Hemangioma of the humerus: value of imaging].

Hemangioma is an uncommon bone neoplasm that usually affects the craniofacial bones and spine, accounting for less than 1% of all primary bone tumors. The authors report a case of isolated hemangioma involving the proximal humerus in a 22-year-old man. Radiographically, the lesion was a well-defined osteolytic process with marginal sclerosis. The CT images demonstrated an osteolytic lesion with coarse trabecular pattern and partial cortical breakthrough. Magnetic resonance imaging showed a multilocular and hemorrhagic lesion with fluid-fluid level, that was suggestive of aneurysmal bone cyst.
