Culture-Proven Disseminated and Meningeal Histoplasmosis Presenting as Septic Shock and Autoimmune Hemolytic Anemia in an Infant

Abstract

Disseminated histoplasmosis is the most common clinical presentation of histoplasmosis in human immunodeficiency virus (HIV) negative infants from Costa Rica and Latin America. Initial presentation as septic shock and autoimmune hemolytic anemia is uncommon. Even more, detection of Histoplasma capsulatum by culture in peripheral blood and cerebrospinal fluid (CSF) is extremely rare. We describe the case of a three-month-old Costa Rican immunocompetent infant who presented with shock and hemolytic anemia secondary to disseminated histoplasmosis that was confirmed by bone marrow aspirate and positive peripheral blood and CSF cultures.
