Chronic Meningoencephalitis due to Cytomegalovirus Infection in a Nonimmunocompromised Patient: An Autopsy Case

Abstract

Congenital cytomegalovirus infection, which is the most common of the intrauterine viral infections, is well known to involve various organs, including the central nervous system. On the other hand, encephalitis due to persistent or acquired infection by cytomegalovirus in the central nervous system is thought to be rare, and to be seen exclusively in immunocompromised patients such as those under immunosuppressant therapy or those with acquired immunodeficiency syndrome (AIDS). We describe chronic meningoencephalitis possibly due to cytomegalovirus seen in an immunocompetent patient with behavior problems.
