Post-meningitic Hydrocephalus for Hydrocephalus and Shunts

Hydrocephalus may occur as the result of a

range of infectious or inflammatory processes. The effects of chronic inflammation – organiza- tion of the inflammatory exudate with scarring or gliosis – can produce obstruction to CSF flow, both within the ventricular system and in the basal cisterns and cortical subarachnoid spaces. Bacterial, parasitic and granulomatous infec- tions are much more likely to lead to hydro- cephalus than viral infections. Ventricular enlargement rather than hydrocephalus may occur due to an ex-vacuo phenomenon. This is a result of the severe white matter damage or encephalomalacia that is commonly seen in the
