Schwannomas are benign tumors arising from Schwann cells which are a protective casing of nerves, composing myelin sheath and can develop in any nerve where Schwann cells are present. Most common are vestibulocochlear nerve schwannomas. Facial nerve schwannomas (FNSs) are uncommon tumors involving seventh nerve of which geniculate ganglion involvement is most common. Clinical presentations and the imaging appearances of FNSs are influenced by the topographical anatomy of the facial nerve and vary according to the segments involved. We report a case of 73-year-old man presenting with right side facial weakness of lower motor neuron type involvement. Computed tomography and magnetic resonance imaging are clinching the diagnosis. An early diagnosis is important in containing the disease facilitating early surgical intervention.
施万细胞瘤是起源于施万细胞的良性肿瘤，施万细胞是神经的保护鞘，构成髓鞘，可在任何存在施万细胞的神经中发生。最常见的是前庭蜗神经施万细胞瘤。面神经施万细胞瘤（FNS）是累及第七神经的罕见肿瘤，其中膝状神经节受累最为常见。FNS的临床表现和影像学表现受面神经局部解剖结构的影响，并根据受累节段而有所不同。我们报告一例73岁男性患者，表现为右侧下运动神经元型面神经麻痹。计算机断层扫描和磁共振成像确诊了该病。早期诊断对于控制病情、促进早期手术干预很重要。
