The authors report 8 cases of fungal myocarditis discovered at autopsy of a series of 118 patients with AIDS. The cardiac disease was symptomatic and responsible for death in 2 cases. Antemortem diagnosis of fungal infection was made on examination of bronchioloalveolar lavage, the cerebrospinal fluid or gastrointestinal biopsy. The demonstration of intramyocardial pathogens was postmortem in all cases. The organism was Candida albicans in 3 cases, Cryptococcus neoformans in 3 cases, and Aspergillus fumigatus in 2 cases. The lesions were not confined to the heart; multi-visceral fungal involvement was diagnosed at autopsy in all cases. Cryptococcal and Candida myocarditis have already been described in most autopsy series in AIDS, but Aspergillus myocarditis is very rare. These fungal myocarditis are usually clinically latent or masked by neurological or respiratory symptoms.
