There are many causes for the paralysis of the external sciatic popliteal nerve , such as the intraneural ganglion cyst. In this case, we evaluate a 52-year-old woman with no relevant personal record, who was admitted with paresis of the right foot of 4 months of evolution associated with alterations in the sensitivity that rose up to the posterolateral region of the leg. The diagnosis was based on MR and cyst decompression and disconnection of the articular branch. Given the low incidence of these lesions, their origin is still subject to controversy. The most widely accepted theory is the unifying articular theory described by Spinner in the year 2003. Intraneural ganglion cysts must be included in the differential diagnosis of progressive paralysis of the sciatic nerve, lesions of the nerve root at L5 and nerve sheath tumours that start at the lateral compartment of the knee. The treatment of a fibular intraneural ganglion cyst must be surgical and the operation must be performed as soon as possible.
坐骨神经腘外侧支麻痹有多种病因，如神经内腱鞘囊肿。在此病例中，我们评估了一名52岁无相关个人病史的女性，她因右足4个月渐进性麻痹伴感觉改变至小腿后外侧区域入院。诊断基于磁共振成像（MR）以及囊肿减压和关节支离断术。鉴于这些病变的低发病率，其起源仍存在争议。最被广泛接受的理论是2003年斯皮纳（Spinner）描述的统一关节理论。神经内腱鞘囊肿必须列入坐骨神经进行性麻痹、L5神经根病变以及始于膝关节外侧间隙的神经鞘瘤的鉴别诊断中。腓骨神经内腱鞘囊肿的治疗必须采用手术，且应尽早进行。
