Adrenal paracoccidioidomycosis.

Primary adrenal insufficiency is a defect in glucocorticoid, mineralocorticoid and sexual androgens production. Patients with this disorder have low cortisol levels and aldosterone deficiency with concomitant hyponatremia and hyperkalemia. The most common etiology of this disease is the production of antibodies against the enzyme 21 hydroxylase. Another common cause, particularly in low income countries, are infectious diseases. Several micro-organisms have been reported as a causal agent in adrenal insufficiency including Mycobacterium tuberculosis, Mycobacterium avium complex, Neisseria meningitidis, Pseudomonas aeruginosa, Haemophilus influenzae, cytomegalovirus, Pneumocystis jirovecii, Histoplasma capsulatum, Blastomyces dermatiditis, Cryptococcus neoformans, Cocciodiodes immitis, Nocardia spp. and Paracoccidioides brasiliensis. In this article, we present the computerized tomography and the adrenal biopsy of a patient with adrenal insufficiency. The final diagnosis was paracoccidioidomycosis.
