Abstract
- Cryptococcosis is caused by cryptococcus neoformans, a thin walled, nonmycelial, budding yeast 4 to 6 micrometer in diameter that is characterized by a thick polysaccharide capsule. Cryptococcus neoformans is found in soil and other environmental areas, especially those contaminated by pigeon droppings. Cryptococcosis is acquired by inhaling aerosols containing the yeast. Cryptococcal infection results in self-limited pulmonary disease in most healthy persons, but meningoencephalitis is the most commonly recognized manifestation of cryptococcosis and the most common cause of death. We described a case of pulmonary cryptococcosis without specific underlying disease and the literature on subject were reviewed. A fifty year-old previously healthy female presented with coughing and left chest pain for 3 months of duration. She had no history suggesting immunologic suppression and we could not find any abnormal laboratory findings including blood sugar, serum immunoglobulin and complement level, HIV antibody, and T cell subsets. Chest roentgenogram showed soft tissue mass in left lower lobe and chest CT scan showed air-space consolidation in left lower lobe. The diagnosis was made by ultrasound guided transthoracic fine needle aspiration showing numerous fungal spores with polysaccharide capsule.
