Though osteoid osteoma is a common primary benign lesion of the bones, intra-articular involvement is rare and poses diagnostic difficulties when it affects middle-aged patients. We present the case of a 51-year-old woman with a 2.5 year history of anterior knee pain that was misdiagnosed as osteochondritis dissecans. Radiological findings were absent, whereas MRI showed a well-circumscribed lesion. A local excisional biopsy was performed and microscopic appearance confirmed diagnosis.
虽然骨样骨瘤是一种常见的原发性骨良性病变，但关节内受累情况罕见，当其影响中年患者时会造成诊断困难。我们报告一例51岁女性患者，有2.5年的前膝疼痛病史，最初被误诊为剥脱性骨软骨炎。影像学检查未发现异常，而磁共振成像（MRI）显示有一个边界清晰的病灶。进行了局部切除活检，显微镜下表现确诊了病情。
