A 56-year-old hypertensive man suddenly developed difficulty in speaking and numbness in the right hand. On admission, he showed moderate right supranuclear facial palsy and right clumsy hand. Three weeks later, he was discharged with only right supranuclear facial palsy. MRI revealed a small infarction in the middle pons. The lesion was situated in the paramedian borderzone between the base and tegmentum. These findings suggest that supranuclear fibers to the facial nucleus descend as a separate bundle from the main pyramidal tract at the mid-pontine level.
一名56岁的高血压男性突然出现言语困难和右手麻木。入院时,他表现为中度右侧核上性面瘫和右手笨拙。三周后,他出院时仅遗留右侧核上性面瘫。磁共振成像(MRI)显示脑桥中部有一个小梗死灶。病变位于脑桥基底部与被盖部之间的旁正中边缘带。这些发现提示,至面神经核的核上纤维在脑桥中部水平从主要锥体束分出,单独下行。
