title: Ventriculitis in an adult delineated by radionuclide brain scan: association with misleading findings on computerized tomography.
abstract: We describe subacute periventricular encephalitis manifesting as dementia in an adult with a radionuclide brain scan showing "ventriculitis." Cranial computed tomography erroneously indicated an infiltrative tumor. We emphasize the use of conservative management rather than surgical exploration.
