Ventriculitis is the inflammation of the ependymal lining of the cerebral ventricles, usually secondary to infection. It has other names, such as ependymitis, ventricular empyema, pyocephalus, and pyogenic ventriculitis. It is an indolent but lethal infection and a source of persistent infection following meningitis treatment. Early diagnosis is essential for appropriate treatment. It is of particular concern in patients with external ventricular drains (EVDs) or intraventricular shunts.
