Cryptococcosis

Cryptococcosis is a fungal infection caused by Cryptococcus neoformans, a world-wide distribution fungus which is commonly found in soil, especially that containing pigeon and avian droppings. Infection is acquired by inhaling spores of fungus 1

Epidemiology

Occur worldwide without any defined endemic areas. Cryptococcal infections in humans likely occur when the organism is aerosolized and inhaled 3.

Clinical presentation

The lungs, central nervous system, blood, skin, bone, joints, and prostate are the most commonly involved sites.

It occurs predominantly in immunocompromised patients but can also be seen in the normal host. 

  • immunocompetent host : cryptococcal infections are commonly localized to the lung and the patients are asymptomatic1
  • immunocompromised patient : cryptococcal infections often cause symptomatic pulmonary infections and then often disseminate to the central nervous system, skin, and bones1.

In fact, central nervous system infection after haematogenous dissemination is more common than pulmonary infection.
