Intraventricular hemorrhage: bleeding into the ventricles

Lateral Ventricle: one of two normal cavities within the cerebral hemispheres that contains cerebrospinal fluid. CSF flows from the lateral ventricles into the third ventricle via the foramen of Monro

Meninges: membranous coverings of the brain and spinal cord consisting of the dura mater, arachnoid and pia mater.

Meningitis: inflammation of the meninges. Meningitis can result from bacterial or viral infection. Scarring of the arachnoid that results from meningitis can restrict or block CSF flow and absorption.
