Bell's palsy (idiopathic facial paralysis) is the most common cause of unilateral peripheral facial neuropathy. Bilateral involvement occurs in less than 10% of cases. The authors describe a 20-year-old man with bilateral idiopathic facial weakness. Brain magnetic resonance imaging (MRI) showed abnormal bilateral enhancement of the proximal intracanalicular segments of VII/VIII nerve complexes. The enhancement was most prominent in the leptomeningeal regions. There was no facial nerve swelling. Three months later he had improving residual bifacial weakness. To the authors' knowledge, this is the first report of abnormal MRI findings in bilateral Bell's palsy.
贝尔麻痹（特发性面神经麻痹）是单侧周围性面神经病变最常见的病因。双侧受累病例不到10%。作者描述了一名20岁双侧特发性面部无力的男性患者。脑部磁共振成像（MRI）显示双侧VII/ VIII神经复合体近端管内段强化异常。强化在软脑膜区域最为显著。面神经无肿胀。三个月后，他双侧面部残留无力有所改善。据作者所知，这是双侧贝尔麻痹MRI异常表现的首例报道。
