Entrapment of the Temporal Horn: A Form of Focal Non-communicating Hydrocephalus Caused by Intraventricular Block of Cerebrospinal Fluid Flow — Report of Two Cases —

Abstract

In two cases of entrapment of the temporal horn, computed tomography demonstrated the typical appearance of a comma-shaped homogeneous area isodense with water surrounded by a periventricular low-density area. The cause was probably choroid plexitis resulting in obstruction of the cerebro spinal fluid pathway at the atrium. External drainage followed by shunt emplacement is indicated. © 1992, The Japan Neurosurgical Society. All rights reserved.
