Overview

Ventricular enlargement not entirely attributable to cerebral atrophy or congenital enlargement (Evans index >0.3). No macroscopic obstruction to CSF flow. Enlargement of the temporal horns of the lateral ventricles not entirely attributable to hippocampus atrophy. Callosal angle of 40º or greater. Evidence of altered brain water content, including periventricular signal changes on CT and MRI not attributable to microvascular ischemic changes or demyelination. An aqueductal or fourth ventricular flow void.

CT

  • The Ct scan findings are given below:[1][2][3]
  • Ventricular enlargement not entirely attributable to cerebral atrophy or congenital enlargement (Evans index >0.3).
