title: Claude's Syndrome without Ptosis Caused by a Midbrain Infarction.
abstract: An 80-year-old man with angina pectoris abruptly developed Claude's syndrome, which consisted of left-sided partial oculomotor nerve palsy without ptosis and right-sided hemiataxia. There were no other neurological abnormalities. Cranial magnetic resonance imaging indicated an infarction of the left inferior paramedian mesencephalic artery, which may have involved the most caudal portion of the oculomotor fascicules. With anti-platelet therapy, the patient became asymptomatic within 10 days. The oculomotor fascicular arrangement in humans remains unclear. Our case suggests that in the oculomotor fascicles, the fibers to the levator palpebrae superioris may be located more in the rostral region than previously hypothesized.
