The brain and the brain stem were investigated by magnetic resonance (MR) in 19 patients with complete acute peripheral facial palsy, diagnosed as Bell's palsy. Five patients with a median age of 57 years had changes on T2 weighted MR: One patient showed transient signal changes with increased signal intensity in the ipsilateral brain stem. Another patient had persisting abnormal signals both in the brain and the brain stem. Two patients presented regions of high signal intensity in the subcortical cerebral white matter and still another patient had increased signal intensity in the periventricular white matter. MR abnormalities anatomically related to the facial nerve or its nucleus were not demonstrated. The significance of the MR findings is not quite certain but the MR pattern in conjunction with the patient's high median age most likely indicate vascular disease.
对19例被诊断为贝尔麻痹的急性完全性周围性面瘫患者进行了磁共振（MR）检查，以研究其大脑和脑干情况。5例年龄中位数为57岁的患者在T2加权磁共振成像上有改变：1例患者同侧脑干出现短暂信号改变，信号强度增加。另1例患者大脑和脑干均有持续异常信号。2例患者皮质下脑白质出现高信号区，还有1例患者脑室周围白质信号强度增加。未发现与面神经或其核团在解剖学上相关的磁共振异常。磁共振检查结果的意义尚不完全明确，但结合患者较高的年龄中位数，磁共振表现很可能提示血管疾病。
