Hydrocephalus in TB meningitis on MRI

A T1-weighted MRI of the brain in the sagittal projection shows hydrocephalus of the lateral ventricle (asterisk) and fourth ventricle (arrow). Image B is a FLAIR sequence in axial projection and shows moderate hydrocephalus of the lateral ventricles (asterisks) with trans-ependymal edema (arrows), and diffuse cerebral edema and effacement of the sulci (arrowhead). Image C is a FLAIR sequence showing hydrocephalus of the third ventricle (asterisk), transependymal edema (arrows), and effacement of the sulci (arrowhead) indicating cerebral edema.
