A 63-year-old man presented with the loss of the sensations of pain and temperature sensation in the right facial region innervated by the trigeminal nerve (V1 to 3). He showed abnormal lesions in the pons and the trigeminal nerve on magnetic resonance imaging (MRI). He had recurrent herpes in the nasal cavity, and a history of left facial palsy. We herein present the unique MRI findings and suggest that herpes simplex infection may cause trigeminal neuropathy. This is the first reported case of dissociated trigeminal neuropathy with herpes simplex infection which was accompanied by a pontine lesion on MRI.
一名63岁男性出现由三叉神经（V1至3）支配的右侧面部区域痛觉和温度觉丧失。他的磁共振成像（MRI）显示脑桥和三叉神经有异常病变。他鼻腔反复出现疱疹，并有左侧面瘫病史。我们在此展示独特的MRI表现，并提示单纯疱疹感染可能导致三叉神经病变。这是首例报道的伴有MRI脑桥病变的单纯疱疹感染所致分离性三叉神经病变病例。
