Facio-Oculo-Palatal Myoclonus Complicated by a Recurrent Brainstem Stroke.

A 54-year-old Thai male who has suffered from multiple episodes of ischemic and hemorrhagic strokes developed facio-oculo-palatal myoclonus (FOPM) 1 month after the latest episode of the brainstem stroke.The patient presented with semirhythmic, involuntary, horizontal jerky, and rotatory ocular oscillation concomitant with asymmetrical palatal and perioral myoclonus consistent with FOPM.FOPM is a useful clinical clue for diagnosing brainstem lesions, specifically in the Guillain-Mollaret triangle. The commonest etiology is cerebrovascular diseases.
