Coccidioidomycosis is a dimorphic fungus endemic to the southwestern United States, Central and South America. We report a case of a previously healthy person who presented with respiratory failure and disseminated Coccidioidomycosis who eventually had a fatal outcome. Coccidioidomycosis, or “Valley Fever” has been called the “great imitator” (1) as it can have a wide variety of clinical presentations. This case is unique as it represents the first described case of an immunocompetent host with rapidly progressing, disseminated coccidioidomycosis with clinically apparent splenomegaly and hepatomegaly.
