Intra-Articular Subtalar Osteoid Osteoma of the Talus: A Case Report

Barbara Pierre Louis, Prianka Belancourt, Rull James Toussaint

Case: A 17-year-old boy, a competitive runner, presented with a right ankle sprain leading to progressive activitylimiting pain despite non-surgical treatment. Imaging at the initial presentation, two years before surgery, suggested a lateral talar process stress reaction. Subsequently, preoperative MRI imaging revealed an intra-articular talar mass at the anterior aspect of the subtalar joint. The patient underwent en-bloc resection of the osteoid osteoma with complete resolution of symptoms. 

Conclusion: Progressive ankle and hind foot pain should be followed closely and evaluated in-depth with serial advanced imaging using either computed tomography or magnetic resonance imaging to rule out the development of neoplastic processes
