Reveal Findings

x ray – spicuated expansile lesion of the 1st metacarpal.

CT – striated osteolysis of the cortex with resorbed trabeculae.

Reveal Discussion

Sekeletal hemangiomas account for approximately 1% of primary bone tumors. The vast majority occur in the axial skeleton (skull, vertebrae, pelvis, ribs, clavicles, and scapulae). Hemangiomas of the appendicular skeleton often have bizarre aggressive appearances. Most appendicular hemangiomas originate from the medullary space but can arise from the cortex or periosteum. Almost all patients do well, even with incomplete resection.

Reveal Diagnosis

Hemangioma with aneurysmal bone cyst formation.
