Background:
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.
Phenomenology shown:
The patient presented with semirhythmic, involuntary, horizontal jerky, and rotatory ocular oscillation concomitant with asymmetrical palatal and perioral myoclonus consistent with FOPM.
Educational value:
FOPM is a useful clinical clue for diagnosing brainstem lesions, specifically in the Guillain-Mollaret triangle. The commonest etiology is cerebrovascular diseases.
