Cryptococcal brain lesions, illustration - stock illustration

Cryptococcal brain lesions. Illustration of multiple brain parenchyma lesions caused by the fungus Cryptococcus neoformans and a close-up view of the fungus. C. neoformans is a yeast-like organism. Cryptococcosis is a rare infection that affects people with a deficient immune system such as in AIDS (acquired immunodeficiency syndrome). It is caused by inhaling the fungus found in soil contaminated by pigeon droppings. Infection may cause meningitis, or single or multiple lesions in brain parenchyma. Cryptococcus neoformans var. gattii more commonly produces parenchyma lesions while Cryptococcus neoformans var. neoformans commonly produces meningitis.
