[Mimikry of herpes encephalitis by glioblastoma multiforme]

Herpes encephalitis (HSE) is an acute illness. Imaging is an important part of the diagnostic work-up of HSE. In early stages one can see a manifestation in the insular cortex as well as in the fornix. These MRI findings are rather typical for HSE. We present three cases treated in our hospital over the past ten years. In these cases the clinical symptoms and signs as well as the morphological findings were compatible with the HSE diagnostic criteria. Later on, a glioblastoma multiforme was found in all three cases.
