Juxta-articular localization is not exceptional for an osteoid osteoma of the ankle. Arthroscopic treatment has been recently proposed. A case of recurrence of an osteoid osteoma at the talar neck is reported after arthroscopic resection performed following a diagnosis failure. The need for accurate imaging technique to precisely define and localize the nidus and the requirement to include osteoid osteoma in the differential diagnosis of monoarticular pain are discussed.
