Abstract

Brainstem lesions may produce a cheiro-oral syndrome infrequently. The cheiro-oral syndrome in pontine lesion is due to involvement of ventral trigeminothalamic tract and the medial part of the medial lemniscus. The cheiro-oral syndrome rarely associates with internuclear ophthalmoplegia. A 58-year-old hypertensive man complained of dizziness, diplopia, and dysesthesia in the right hand and ipsilateral perioral region. On neurologic examination, there was left internuclear ophthalmoplegia. Others were unremarkable. Brain MRI demonstrated a small round lesion in the paramedian tegmentum of the left upper pons and lower midbrain, which involved ventral trigeminothalamic tract, medial part of medial lemniscus and medial longitudinal fasciculus. We report a case of brainstem infarction with a rare combination of cheiro-oral syndrome and internuclear ophthalmoplegia. Key Words : Cheiro-oral syndrome, INO, Stem infarction
