Overview
Diagnostic Study of Choice
Study of choice
- MRI is the gold standard test for the diagnosis of hydrocephalus, the findings are given below:[1][2][3]
- Ventricular enlargement not entirely attributable to cerebral atrophy or congenital enlargement (Evans index >0.3).
- No macroscopic obstruction to CSF flow.
At least one of the following supportive features: 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.
