[Demonstration of Cryptococcus neoformans in a fatal meningeal disease in the Congo].

Cryptococcus neoformans, mainly widespread in Occidental Europe, America and South East of Asia, was rarely described in African pathology. In Central Africa, it was isolated several times in Zaïre. All reported cases concern young people and present no associated pathology. A first fatal case, looking like an acute meningitis, was described in 1959, in a 18 years old Congolese girl. This second case discovered in Brazzaville in a 37 years old young man was a fatal encephalitis after a primary pneumopathy.
