Abstract：
Popliteal cysts are a collection of synovial fluid found in the popliteal fossa that typically form in adults in association with traumatic injuries, degenerative conditions, or inflammatory arthritis of the knee. While often asymptomatic, popliteal cysts may become problematic as enlarging and ruptured cysts may compress surrounding neurovascular structures, resulting in lower extremity edema or peripheral neuropathy. We report a unique case of a symptomatic popliteal cyst in a patient with both compressive neuropathy and venous congestion in the setting of a non-ruptured popliteal cyst after a surgically repaired intraarticular injury. Magnetic resonance imaging (MRI) showed a synovial cyst abutting the posterior neurovascular bundle and evidence of avascular necrosis. An open posterior cyst decompression was done, and the patient was able to report significant symptomatic improvement over the course of two weeks postoperatively. The previously noted varicose veins also demonstrated noticeable resolution. While relatively common, popliteal cysts may require prompt surgical decompression in order to provide effective symptomatic relief.
摘要：
pop囊肿是在pop窝中发现的滑液的集合，通常在成年人中与创伤性损伤有关，退化状态,或者膝盖的炎性关节炎.虽然经常无症状，由于囊肿扩大和破裂可能会压迫周围的神经血管结构，导致下肢水肿或周围神经病变。我们报告了一个独特的病例，即在手术修复的关节内损伤后，在未破裂的pop囊肿中，患有压迫性神经病和静脉充血的患者中，有症状的pop囊肿。磁共振成像（MRI）显示滑膜囊肿邻接后神经血管束，并有缺血性坏死的证据。行开放性后囊肿减压术，患者在术后两周内报告症状明显改善。先前提到的静脉曲张也显示出明显的分辨率。虽然比较常见,pop囊肿可能需要及时手术减压以提供有效的症状缓解。
