Abstract:
An aneurysmal bone cyst is a benign solitary lesion of unknown etiology. A case report is presented of recurrence of an aneurysmal bone cyst in the foot that was treated with endoscopic curettage without bone grafting. Bone remodeling and bone formation were completed in the early stages postsurgically. At 2-year follow-up, the patient is asymptomatic with no radiographic evidence of recurrence.
