Osteoid osteoma is a painful, benign bony tumor affecting a predominantly young patient population, with 60% occurring between ages 10 and 20 years old and a male predominance. Nocturnal and rest pain are hallmarks. Symptoms vary from a mild ache to severe debilitating pain in response to excessive prostaglandin production. As such, the pain is classically responsive to aspirin due to its anti-prostaglandin effect. Localized swelling and tenderness may be present on examination. Radiographically, osteoid osteoma is traditionally described as a 1–2-cm radiolucent lesion with a sclerotic border and central nidus consisting of vascular osteoid with focal mineralization. Imaging modalities including radiographs, bone scan, CT, and MRI can be helpful in the diagnosis of osteoid osteoma.
