Abstract

Unilateral hydrocephalus is a unique condition, the more so when limited to a portion of one ventricle. By unilateral hydrocephalus is ordinarily meant a condition that results from obstruction at the foramen of Monro. It differs but little from the bilateral type, except that in the latter the obstruction is lower down. The mechanism of these obstructive forms has been shown by Dandy.1 But when the condition is unilateral and no obstruction is present, further study must be made to determine its cause. Such a study forms the basis of this report.
