摘　　要：单侧下肢无力以足下垂较为常见,主要表现为踝关节背伸无力(主要是胫骨前肌)。最常见的病因包括腓总神经麻痹、L5神经根损害、肌病等。但是中枢性原因导致的足下垂较为罕见。作者在临床工作中遇到1例43岁患者以孤立性足下垂为主要表现,在经过相关检查[神经传导速度测定、肌电图、磁共振成像(MRI)及病理学检查]确诊为矢状窦旁脑膜瘤。此类病因引起的孤立性足下垂较为罕见,需引起同行重视,以免延误病情。Unilateral lower extremity weakness is more common with foot drop,which is mainly manifested by weakness of dorsiflexion of the ankle joint(mainly anterior tibial muscle).The most common causes include common peroneal nerve palsy,L5 nerve root damage,and myopathy.However,central causes of foot drop are rare.In clinical work,the author encountered a 43-year-old patient with isolated foot drop as the main manifestation,and the diagnosis of parasagittal meningioma was confirmed after relevant examinations[nerve conduction velocity measurement,electromyogram,magnetic resonance imaging(MRI)and pathology].Isolated foot drop of this etiology is rare and needs to be taken into account by colleagues to avoid delaying the disease.
