Intra-abdominal cryptococcosis by Cryptococcus gattii: case report and review

Abstract

Although abdominal cryptococcomas and visceral cryptococcal lymphadenitis as part of disseminated fungal infection have been reported mostly in HIV-infected patients, localized intra-abdominal involvement due to Cryptococcus gattii has not been previously described in non-HIV-infected patients. In general, a smaller proportion of cryptococcosis is caused by C. gattii. We report here on a type II diabetic HIV-negative patient who presented with a localized intra-abdominal cryptococcal mass due to C. gattii. In addition, we review the general aspects of intra-abdominal and gastrointestinal involvement by Cryptococcus neoformans in the literature and discuss the importance of identifying the C. neoformans varieties and C. gattii in routine laboratories.
