We report the case of an active 8-year-old boy with a history of hemophilia and with a 1-year history of knee pain and limited range of motion. Magnetic resonance imaging of the knee demonstrated a ganglion cyst arising from the posterior cruciate ligament (PCL). Arthroscopic decompression of the cyst was performed, and he was asymptomatic at the 1-year follow-up.
This case demonstrates a rare finding of a pediatric PCL ganglion cyst. We suggest that clinicians should be aware of this as a cause of knee pain in the pediatric population and that arthroscopic management can be successful.
我们报告了一例患有血友病的活跃 8 岁男孩，他有 1 年的膝关节疼痛和活动范围受限病史。膝关节磁共振成像显示后交叉韧带（PCL）处有一个腱鞘囊肿。对囊肿进行了关节镜减压，1 年随访时他无症状。
本病例显示了儿童 PCL 腱鞘囊肿的罕见表现。我们建议临床医生应意识到这是儿童膝关节疼痛的一个原因，并且关节镜治疗可以成功。
