We report a case of left-sided horizontal gaze palsy, ipsilateral adduction weakness, and left peripheral facial weakness, all of which indicate the lesion in the left median pontine tegmentum. The enhanced MRIs revealed a discrete left median pontine tegmental lesion, involving the abducens nucleus, MLF, and facial nerve knee. This lesion spared the area of the left PPRF. Among these structures, the area of the abducens nucleus seems to be responsible for the unilateral horizontal gaze palsy. We are not aware of any previous precise neuroradiological documentation of unilateral paralysis of conjugate gaze due to a lesion of the abducens nucleus by sagittal and horizontal MRIs.
我们报告一例左侧水平凝视麻痹、同侧内收无力及左侧周围性面瘫病例，所有这些均提示左侧脑桥被盖部正中病变。增强磁共振成像显示左侧脑桥被盖部正中存在一个离散性病变，累及展神经核、内侧纵束及面神经膝部。该病变未累及左侧脑桥旁正中网状结构区域。在这些结构中，展神经核区域似乎是导致单侧水平凝视麻痹的原因。我们未发现之前有通过矢状位和水平位磁共振成像对因展神经核病变导致的共轭凝视单侧麻痹进行精确神经放射学记录的相关报道。
