Result of arthroscopic removal of an enchondroma at the talar dome: a case report.

Enchondroma is a benign tumor that is generally asymptomatic and rarely found in the talus. A forty-nine-year-old man, had a chronic left ankle pain which related to moderate to heavy activity. A plain radiograph and magnetic resonance imaging (MRI) revealed a 1.3 cm benign lobulated intramedullary lesion at the middle 1/3 of medial part of talar dome with sclerotic rim. An arthroscopic intralesional curettage of the ankle joint was performed without bone grafting. Histologic examination was consistent with the diagnosis of an enchondroma. The patient was asymptomatic and without restriction on his job at 6 months. At 1 year of follow-up, the CT scan and MRI demonstrated no recurrence of the tumor but the defect was not filled up.
