title: Cytomegalovirus infection of the brain in AIDS: a clinicopathological study.
abstract: Based on neuropathological findings, a retrospective case control study of 39 patients with acquired immune deficiency syndrome (AIDS) and confirmed cytomegalovirus (CMV) infection of the brain is presented. Since 1989, the incidence has increased progressively and, in 1994, CMV was the most frequent opportunistic central nervous system (CNS) infection. Of the patients with CMV infections of the brain 16 had one or more coexisting secondary opportunistic and/or tumorous lesions in the CNS. Cerebral involvement by CMV was more frequent in patients with multiple extracerebral organ infections, while 7 among the 39 reported cases showed isolated CMV infection of the brain. The evaluation of the clinical records of 21 patients revealed neuropsychiatric signs and symptoms in 10, while these were absent in 11. All of these patients revealed various types of cerebral lesions related to CMV infection: ventriculitis, focal lesions, and microglial nodule encephalitis. The extent and distribution of cerebral lesions showed no significant correlations with clinical, radiological, or laboratory findings. Further clinicopathological studies are warranted to recognize CMV infections of the CNS and to allow earlier and more efficient treatment of this rather frequent complication of AIDS.
