A Large Ankle Mass in a Figure Skater: A Case Report.

ABSTRACT

A 19-year-old male competitive figure skater presented to clinic with a 3-year history of right ankle swelling. Exam demonstrated a ~6cm diameter mass over the medial malleolus. MRI revealed a well-circumscribed fluid-filled mass. After failing conservative management, the patient underwent surgical excision. Anatomic pathology revealed a pseudocyst with pseudosynovial metaplasia, consistent with malleolar bursitis. Competitive figure skaters can develop significant medial malleolar bursitis due to excessive shear forces from ill-fitting skates. If non-operative management is ineffective, patients can be managed successfully with surgical excision. The patient made a full recovery and has returned to competitive skating without recurrence.
