"Eight-and-a-half" syndrome is "one-and-a-half" syndrome (conjugated horizontal gaze palsy and internuclear ophthalmoplegia) plus ipsilateral fascicular cranial nerve seventh palsy. This rare condition, particularly when isolated, is caused by circumscribed lesions of the pontine tegmentum involving the abducens nucleus, the ipsilateral medial longitudinal fasciculus, and the adjacent facial colliculus. Its recognition is therefore of considerable diagnostic value. We report a case of a 65-year-old man who presented with eight-and-a-half syndrome in which brain magnetic resonance imaging scan revealed a lacunar pontine infarction.
“8.5综合征”是“1.5综合征”（共轭性水平凝视麻痹和核间性眼肌麻痹）加同侧面神经束性麻痹。这种罕见病症，尤其是孤立出现时，是由脑桥被盖部局限性病变累及外展神经核、同侧内侧纵束及相邻面丘所致。因此，对其识别具有重要的诊断价值。我们报告一例65岁男性患者，表现为8.5综合征，脑部磁共振成像扫描显示为腔隙性脑桥梗死。
