title: Subperiosteal osteoid osteoma of the neck of talus.
abstract: Juxta-articular, subperiosteal osteoid osteomas arising around the ankle are unusual. Tumors arising on the neck of the talus commonly produce symptoms mimicking monoarticular arthritis. Patients are usually treated for arthritis or ankle sprain, which often leads to a delay in definitive diagnosis. Here we present a case of osteoid osteoma of neck of talus which was presented as ankle pain. It puzzled us until MRI was done. Diagnostic dilemma and delay can be avoided by high index of suspicion. The patient was treated with open removal of the tumor. We also present brief review of literature about juxta-articular, subperiosteal osteoid osteoma which is uncommon from the typical osteoid osteoma occurring elsewhere in the body.
