Answer

Ventriculomegaly can occur early or late in the course of meningitis and is usually transient and mild to moderate in severity. As a result of the subarachnoid inflammatory exudate, CSF pathways may become obstructed, leading to hydrocephalus. Exudates in the foramina of Luschka and Magendie can cause noncommunicating hydrocephalus, whereas exudates that accumulate in the basilar cisterns or over the cerebral convexity can develop into communicating hydrocephalus.
