Cryptococcosis is transmitted through inhalation, mainly affects the lungs, and causes infection. A large number of patients have asymptomatic, self-limiting primary lung infections. Even without antifungal medication, these isolated pulmonary diseases in immunocompetent individuals usually heal spontaneously without spreading.
A fungus named Cryptococcus neoformans causes cryptococcosis. This infection spreads through exposure to pigeon excrement, unwashed raw produce, or sick individuals. People with weaker immune systems, undergoing organ transplants, cancer treatment, and those diagnosed with HIV-AIDS are more vulnerable to this fungus infection.
After acquiring cryptococcus through inhalation, it can spread from the lungs to the brain, meninges and cause tiny multifocal intracerebral lesions. It’s possible to see meningeal granulomas and bigger concentrated brain lesions. Although lung involvement is rare, cryptococcal meningitis is fatal and needs intensive treatment.
