Meralgia paresthetica is commonly caused by a focal entrapment of lateral femoral cuteneous nerve while it passes the inguinal ligament. Common symptoms are paresthesias and numbness of the upper lateral thigh area. Pregnancy, tight cloths, obesity, position of surgery and the tumor in the retroperitoneal space could be causes of meralgia paresthetica. A 29-year-old female patient underwent an emergency cesarean section under spinal anesthesia without any problems. But two days after surgery, the patient complained numbness and paresthesia in anterolateral thigh area. Various neurological examinations and L-spine MRI images were all normal, but the symptoms persisted for a few days. Then, electromyogram and nerve conduction velocity test of the trunk and both legs were performed. Test results showed left lateral cutaneous nerve injury and meralgia paresthetica was diagnosed. Conservative treatment was implemented and the patient was free of symptoms after 1 month follow-up.
股外侧皮神经炎多由股外侧皮神经在穿过腹股沟韧带处受到卡压引起，常见症状为大腿外侧上部感觉异常和麻木。妊娠、紧身衣物、肥胖、手术体位和腹膜后间隙肿瘤均可导致股外侧皮神经炎。一位 29 岁女性患者在蛛网膜下腔麻醉下行急诊剖宫产术，过程顺利。但术后 2 天，患者诉大腿前外侧麻木感和感觉异常。各种神经学检查和 L 脊柱 MRI 图像均正常，但症状持续数天。随后，进行了躯干和双下肢肌电图和神经传导速度检查。检查结果显示左侧皮神经损伤，诊断为股外侧皮神经炎。给予保守治疗，1 个月后随访时患者症状消失。
