Herpes simplex encephalitis is a rare disease. In adults, most of the reported cytomegalovirus (CMV) infections are seen in immunocompromised patients. We present a case of 67-year-old Chinese male with the coinfection of CMV and herpes simplex virus type II (HSV-II). He had no history of being treated with immunosuppressants, showed symptoms of psychosis and was scored 109 on the Positive and Negative Syndrome Scale. This patient presented with a rare case of coinfection of CMV and herpes simplex virus type II with psychotic symptoms.
