Popliteal cysts occur commonly in both normal and arthritic knees. Most cysts are formed by distension of the medially situated semimembranosus bursa. Popliteus bursa distension occurs uncommonly as a lateral popliteal cyst. Two cases of rupture of lateral cysts which produced symptoms related to the anterolateral lower leg are reported. The difficulty of diagnosing the condition because of this unusual site of inflammation and subsequent management problems are discussed.
腘窝囊肿在正常膝关节和患有关节炎的膝关节中都很常见。大多数囊肿是由位于内侧的半膜肌滑囊扩张形成的。腘肌滑囊扩张作为外侧腘窝囊肿很少见。本文报告了两例外侧囊肿破裂并产生与小腿前外侧相关症状的病例。文中讨论了由于这种不寻常的炎症部位导致的诊断困难以及后续的治疗问题。
