Hypoadrenal crisis caused by disseminated histoplasmosis

We report a case of disseminated histoplasmosis presenting with acute renal impairment due to adrenal insufficiency. The finding of bilateral adrenal gland enlargement on abdominal ultrasound examination led to a diagnostic CT-guided adrenal biopsy. Prolonged therapy with amphotericin and itraconazole resulted in a clinical cure, although the patient still requires adrenal replacement therapy.
