비마비성뇌교 외사시를 보인 뇌간부 경색 1례

Abstract

Paralytic pontine extropia(PPE) is a exotropia in contralateral eye of lesion side, associated with one-and- a-half syndrome in acute phase of brainstem infarction and after then, often followed by non-paralytic pontine extropia(NPPE) and medial longitudinal fasciculus (MLF) syndrome in each clinical improvement. NPPE is pontine exotropia without lateral gaze palsy to ipsilateral side and is considered to be due to partial impairment of the unilateral paramedian pontine reticular formation(PPRF). We reported a case, 75 yearold man, of brainstem infarction who initially presented NPPE in acute phase, followed by ipsialteral MLF syndrome after 5th days.
