Intraosseous gouty invasion of the talus.
A 34-year-old man presents with a cystic lesion of the talus that has developed over the last 3 years and a history of a single first metatarsophalangeal attack of gout. Radiodiagnostic studies confirmed the cyst and an associated osteochondritic lesion but showed no evidence of avascular necrosis. At arthroscopy, chalk-like material was removed from the cyst, which was histologically compatible with tophaceous gout. The lesion was debrided, and the patient was then treated with antihyperuricemic medication; radiographic evidence of cyst resorption was seen after 9 months of treatment.
