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.
