An angiostatic agent in treatment of a recurrent aneurysmal bone cyst

Healing of an aggressive recurrent aneurysmal bone cyst of the distal humerus was induced by oral dexamethasone, an angiostatic agent. The severe pain and tenderness resolved rapidly. The soft tissue swelling subsided, and a thick layer of bone formed around the cyst. Complete healing followed saucerization and curettage of the remaining vascular tissue in the center of the cyst. We suggest that angiostatic agents be included in the nonoperative methods of treatment of aggressive aneurysmal bone cysts.
