ABSTRACT: Osteoid osteoma is a benign bone tumor that is commonly seen in males in their second and third decade of life. The tumor commonly occurs in long bones (proximal femur and tibia) and rarely in the spine, hands and feet. It presents with bone pain worsening at night and responds well to nonsteroidal anti-inflammatory drugs. It is usually treated conservatively but sometimes with surgery if medical treatment fails. We present a case of 19-year-old girl, who presented with mild pain over lateral aspect of right ankle for 6 months duration. The pain was provoked by sporting activities, and was initially relieved by analgesics, until recently, hence her presentation. CT scan was done and showed a well-defined central nodule of bone. She had an open excisional biopsy, and the histology showed a diagnosis of osteoid osteoma. Post-operative healing was uneventful, the fracture united after 6 weeks and she was able to ambulate without any pain 3 months post-surgery.
