Mother-to-child transmission of cryptococcus neoformans.

Cryptococcal meningitis was diagnosed in a 92-day-old boy who was not HIV-1-infected and who survived after treatment, although with hydrocephalus. The mother was HIV-1-infected, delivered prematurely, had peripartum cryptococcal meningitis and died 14 days postpartum. There was no other possible source for cryptococcal infection in this infant.
