Laparoscopic Neurolysis of Deep Endometriosis Infiltrating Left Femoral Nerve: Case Report.

Pelvic endometriosis may infiltrate somatic nerves causing severe neuropathic symptoms with a high impact on quality of life. It is a medical condition poorly known, and few published data about involvement of femoral nerve are available. We report an isolated unilateral endometriosis lesion of the left lumbar region infiltrating the femoral nerve in a 38-year-old woman. She described severe dysmenorrhea, dyspareunia, dischezia, and chronic pelvic pain with irradiation to the anterior part of the left thigh. After investigation, it was identified as a 5-centimeter endometriotic nodule involving the femoral nerve and the psoas muscle. The patient was treated by two laparoscopic surgeries with neurolysis of the involved somatic nerve by a multidisciplinary team, with improvement of the symptoms. Laparoscopic neurolysis is the first approach advocated in these cases, leading to relief of neurological symptoms resulting from nerve infiltration by endometriosis.
