Osteoid osteoma of the talus: a clinical case report and literature review

INTRODUCTION AND IMPORTANCE: Osteoid osteoma of the talus is a relatively rare benign tumor. It accounts for 10 to 11 % of all benign bone tumors. It generally affects long bones. In our patient, the initial clinical and radiological presentation led to the suspicion of a giant cell tumor. CASE PRESENTATION: The authors report the case of a 29-year-old patient who presented with chronic pain in the foot and ankle. X-ray and CT scan revealed well-defined lytic lesions of the talus. The treatment was surgical. A hollowing followed by the placement of cement was carried out. The diagnosis of osteoid osteoma was confirmed by pathological examination of the curettage product. The evolution was favorable with no sign of recurrence. CLINICAL DISCUSSION: Treatment for this lesion is primarily surgical. The lesion was managed by curettage followed by cement augmentation. Arthroscopic resection is an increasingly used therapeutic option. CONCLUSION: The outcome is usually favorable with a low risk of recurrence.
