Periventricular Lucency in Computed Tomography of Hydrocephalus and Cerebral Atrophy

Abstract

Periventricular lucency was evaluated in the computed tomography scans of a large group of patients with hypertensive and normal pressure hydeocephalus and cerebral atrophy. Periventricular lucency is most prominent in cases of acute obstructive hydrocephalus in which the periventricular density profile pattern is often linear and steep. This linear profile is due to the disappearance of the ventricular wall as an effective barrier at the level of the superolateral angle of the frontal horn. The features of the periventricular lucency in chronic hydrocephalus in detail.
