Syringomesencephalia. Report of a case

Abstract

A woman had progressive neurologic deterioration attributed to multiple sclerosis. Ophthalmologic findings were consistent with a unilateral lesion of the medial longitudinal fasciculus. Autopsy disclosed a mesencephalic syrinx and cerebellar atrophy secondary to alcoholism. Syringomesencephalia is distinctly uncommon; this is the third known case to our knowledge.
