Cryptococcosis is infection with Cryptococcus neoformans fungus.
Cryptococcus neoformans is the fungus that causes this disease. It is usually found in soil. If you breathe it in, it infects your lungs. The infection may go away on its own, remain in the lungs only, or spread throughout the body (disseminate).
This infection is most often seen in people with a weakened immune system, such as those with HIV infection, taking high doses of corticosteroid medications, cancer chemotherapy, or who have Hodgkin's disease.
Cryptococcus is one of the most common life-threatening fungal infections in people with AIDS.

Amphotericin B can have severe side effects.
Central nervous system involvement often causes death or leads to permanent damage.
Call your health care provider if you develop symptoms of cryptococcosis, especially if you have a weakened immune system.
