Disseminated aspergillosis is very infrequent in patients infected by the human immunodeficiency virus and diagnosis is made usually upon necropsy. The case of a 28 year old male who presented multiple abscesses by Aspergillus sp. in the lung, thyroid glands, spleen, myocardium, pancreas, kidney and in both cerebral hemispheres is presented. The patient also concommitantly showed M. avium in the spleen, liver and central nervous system. The literature was reviewed to evaluate the clinical characteristics and predisposing factors which may contribute to diagnosis and treatment.
