Osteochondroma arising from the tibial tuberosity is very rare. We report such a case which mimicked OsgoodSchlatter's disease in an adolescent. A 12 years-old boy presented with swelling over his right proximal tibia of one year duration associated with pain in the last three months. Examination revealed a 4 x 2cm bony mass arising from the proximal tibia. Radiographs revealed an osteochondroma of the tibial tuberosity. Computer tomography and magnetic resonance imaging confirmed the continuity of the medulla of the bony mass to that of the parent bone. Excision biopsy was done. At the final follow up, he was asymptomatic and returned back to his daily activities. We present this case for its rarity, challenges involved in diagnosis and the difficulties encountered in planning the surgery because of involvement of the apophysis and extensor mechanism attachment in a skeletally immature boy.
起源于胫骨结节的骨软骨瘤非常罕见。我们报告了一例在青少年中表现类似奥斯古德-施拉特病的病例。一名12岁男孩，右胫骨近端肿胀1年，近3个月伴有疼痛。检查发现胫骨近端有一个4×2厘米的骨性肿物。X线片显示胫骨结节骨软骨瘤。计算机断层扫描和磁共振成像证实骨性肿物的髓腔与母骨的髓腔相连。进行了切除活检。在最后一次随访时，他没有症状，恢复了日常活动。我们展示这个病例是因为其罕见性、诊断中涉及的挑战以及由于骨骺和伸肌机制附着点受累，在为一名骨骼未成熟男孩规划手术时遇到的困难。
