Eight syndrome: Horizontal gaze palsy plus ipsilateral seventh nerve palsy

A 62-year-old woman developed a right horizontal gaze palsy and ipsilateral facial nerve palsy due to a right pontine tegmentum infarct. This constitutes a forme fruste of the eight-and-a-half syndrome that we have termed the eight syndrome. addition, she had a right lower motor neuron facial palsy (Fig. 2). Diffusion-weighted imaging identified a small area of restricted diffusion in the dorsal portion of the right pons at the level of the sixth nucleus and facial colliculus consistent with acute ischemia (Fig. 3). The patient’s gaze palsy was resolved at 2 weeks and at 6 months, no facial weakness was present.
