Osteoid osteoma of scaphoid

Osteoid osteoma is infrequently localized to the hand. Initially the lesion may cause nonspecific symptoms. A 14-year-old boy presented with spontaneous onset swelling and pain wrist for 2 months. Initially he was suspected of having tuberculosis, but radiographs revealed a sclerotic lesion of the scaphoid and the sedimentation rate was not high. CT scan of the wrist showed a double-ring sign, indicating osteoid osteoma. Lesion was curetted and the nidus excised. This resulted in rapid resolution of the symptoms.
