title: A case of osteoid osteoma in the distal radius epiphysis with atypical onset.
abstract: We present a 16-year-old male patient, with a history of wrist trauma 3 months prior to admission, presented with widespread swelling, limitation of motion and pain that was unresponsive to anti-inflammatory drugs in the left wrist. A lesion compatible with osteoid osteoma in the distal epiphysis of the left radius was detected radiologically. Diagnosis of osteoid osteoma was confirmed with pathological examination of the lesion. Differential diagnosis is important as the atypical lesion occurred after trauma, making it difficult to distinguish from synovitis and infection in consideration of its location.
