Cytomegalovirus infection of the CNS in non-compromised patients.
2009
Six non-compromised patients with cytomegalovirus (CMV) associated meningoencephalitis are described. CMV was isolated from the cerebrospinal fluid (CSF) in 2/4 cases, while the diagnosis was based on an 8-fold rise in CMV-specific serum IgG antibodies and intrathecal antibody production against CMV in one case. By the polymerase chain reaction (PCR) CMV DNA was detected in the CSF in 5/5 cases and in serum in 3/4 cases. In one patient who had an Influenza A infection, both CMV and Epstein-Barr virus DNA were detected by PCR in the CSF. In 4 patients possible triggering events could be identified. Symptoms and signs indicating a multifocal brain involvement were present in 4 patients. The outcome was generally favourable except for sequelae in form of slight dysphasia in one case.
