Adrenal histoplasmosis: An unusual cause of adrenomegaly.

Histoplasmosis is a geographically restricted form of fungal infection. Adrenal involvement is seen in disseminated disease but sometimes it may be the only site of demonstrable disease. Early diagnosis and treatment may save the patient from catastrophic adrenal insufficiency. We present two patients showing bilateral adrenomegaly on ultrasonography and contrast-enhanced CT, and was diagnosed to have histoplasmosis on fine-needle aspiration cytology.
