Endometriosis of the sciatic nerve is rare but must be included in the differential diagnosis of sciatic pain. Patients present with typical signs and symptoms of sciatica, which are cyclic in nature. Electromyography and computed tomographic scanning are useful in diagnosis. At laparoscopy or laparotomy, a characteristic "pocket sign" is frequently seen, and may be the only clue to the presence of endometriosis. The patient often requires definitive surgery with total abdominal hysterectomy and bilateral salpingo-oophorectomy. However, conservative surgery with excision of the endometriosis from the nerve can be successful in selected patients who wish to preserve reproductive function.
坐骨神经子宫内膜异位症罕见，但坐骨神经痛的鉴别诊断必须考虑该病。患者表现出典型的坐骨神经痛体征和症状，且具有周期性。肌电图和计算机断层扫描有助于诊断。在腹腔镜检查或剖腹手术中，常可见特征性的“袋状征”，这可能是存在子宫内膜异位症的唯一线索。患者通常需要行全腹子宫切除术和双侧输卵管卵巢切除术的确定性手术。然而，对于希望保留生殖功能的特定患者，切除神经上的子宫内膜异位症的保守手术可能会成功。
