Microtubuloreticular structures in the cerebral vasculature of a patient with herpes simplex encephalitis

In this report we will document the presence of microtubuloreticular structure (MTRS) in the cerebral vasculature of a patient who had contracted herpes simplex (HSV) encephalitis. Twenty of twenty-one blood vessels (capillaries, arterioles, venules) contained MTRS within the cytoplasm of endothelial and/or associated cells. The use of this evidence to support a diagnosis of HSV encephalitis is discussed.
