Coccidioidal peritonitis: A rare manifestation of disseminated coccidioidomycosis.

Coccidioidomycosis (CM) is primarily a pulmonary disease but can also present with significant extrapulmonary disease. Extrapulmonary manifestations vary across organ systems, but most frequently presents as infection of the bone, brain and skin. Due to the variety of clinical presentations in disseminated disease, CM can be underrecognized, resulting in a diagnostic conundrum. We report a case of a non-immunocompromised patient initially presenting for weight loss with imaging findings mimicking peritoneal carcinomatosis, ultimately found to have CM with peritoneal involvement.
