Baker cyst is an abnormal enlargement of the gastrocnemius-semimembranous bursa behind the knee joint due to an exit of joint fluid. We herein report a rare case of giant Baker cyst in a rheumatic arthritic female patient. An MRI scan showed a complex, multiloculated cyst measuring 11.8 cm x 4.6 c, x 3.3 cm, arising from the left knee joint. Open surgical excision of the lesion was performed, and no recurrence was observed during the one-year follow up in the Rheumatology and Orthopedics Department. A natural tendency towards intermuscular extension is observed; thus, intramuscular extensions are rarely reported in the literature. To the best of our knowledge, no Baker cyst of such size has been operated in a rheumatoid arthritis patient.
腘窝囊肿是由于关节液流出导致膝关节后方腓肠肌-半膜肌滑囊异常增大。我们在此报告一例风湿性关节炎女性患者的巨大腘窝囊肿罕见病例。磁共振成像扫描显示一个复杂的多房囊肿，大小为11.8厘米×4.6厘米×3.3厘米，起源于左膝关节。对该病变进行了开放性手术切除，在风湿科和骨科的一年随访中未观察到复发。观察到有向肌间延伸的自然倾向；因此，肌间延伸在文献中很少报道。据我们所知，类风湿关节炎患者中尚未有如此大小的腘窝囊肿接受手术治疗。
