In HSV encephalitis, hemorrhagic necrosis of the temporal lobe is characteristic. Histologically, intranuclear inclusions are seen mainly in neurons. Vacuolated neuropil and mild gliosis are associated (HE).   HSV-1 antigen is demonstrated in the nuclei of neurons. The inclusions bodies are immunoreactive (immunostaining).
