[Pulmonary pseudotumor caused by Cryptococcus neoformans].
Since 1923, eight cases of cryptococcosis have been described in Norway, all with meningeal affection. A distinct, solitary infiltration in the upper lobe of the right lung was discovered in a 68 year-old woman. The lobe was extirpated. Microbiological and histological investigations showed infection with Cryptococcus neoformans. No antimycotic treatment was given. Four months later the patient developed osteomyelitis of the skull due to cryptococcosis, and was treated successfully with amphotericin B and flucytosin. Further investigation of the patient revealed a defect in the T-lymphocyte immune system, but it is uncertain whether this was of any significance for the development of the cryptococcus infection.
