Cytomegalovirus encephalitis: diagnosis with clinical approach, EEG and PCR techniques.

Cytomegalovirus (CMV) encephalitis is particularly evident in immunodepressed patients. Often diagnosis is difficult and time-consuming because of the complex basic clinical picture of these patients. We describe the diagnostic steps taken in a case of cytomegalovirus encephalitis affecting an elderly patient, classified as immunodepressed and deceased on the thirty-fifth day of hospitalisation in the intensive care unit due to acute myocardial infarction. Treatment with ganciclovir, 30 mg/kg per day, begun at the time of diagnosis, appears to have had a positive effect on the neurologic symptoms.
