Cryptococcosis is a cosmopolitan fungal serious condition due to an encapsulated yeast Cryptococcus neoformans. This is the systemic fungal infection the most common in HIV infection. This yeast is present in the environment and its main entrance in the body is the respiratory tract. Its gravity is linked to its tropism for the central nervous system. It generally affects subjects with severe deficit of cellular immunity and in particular, patients living with HIV. The diagnosis of neuromeningeal cryptococcosis is based on the detection of encapsulated yeasts at microscopic examination of cerebrospinal fluid, the detection of capsular polysaccharide antigen in serum or cerebrospinal fluid, but especially on the culture. A staging is always essential. The prognosis is severe. The control of intracranial hypertension is a major element of prognosis.
