Neurological manifestations in three German children with AIDS.

We report the neurological findings in two children with AIDS and one child with lesser AIDS. The first patient developed acute encephalopathy 37 months after having received a blood transfusion from a HTLV-III positive donor. CCT showed ring-enhancement and hypodense lesions with homogenous enhancement. Autopsy revealed CNS toxoplasmosis. The second child with AIDS, born to an iv drug-addicted mother, had one seizure at four months of age, but other neurologic signs were absent. She died of pneumonia due to Pneumocystis carinii at seven months of age. Postmortem examination of the brain revealed extensive nerve cell damage in the cerebral cortex and cerebellum, probably due to terminal hypoxemia and not AIDS-related. In both children clinical features of childhood AIDS like failure to thrive, lymphadenopathy, oral thrush and chronic pulmonary infiltrates were absent. The hallmark of the third child's clinical course was a progressive loss of psychomotor abilities with onset of the neurological symptoms nine months before other signs of AIDS occurred. AIDS should be suspected or excluded in children at increased risk for AIDS presenting with either acquired atypical CNS infection or unexplained developmental regression, even in the absence of other clinical symptoms of pediatric AIDS.
