RESUMO
Involvement of the myocardium by Toxoplasma gondii is seen in patients of acquired immunodeficiency syndrome (AIDS), mostly in association with toxoplasma encephalitis. Only few patients die as a direct result of cardiac dysfunction. Clinico-pathological findings of three cases of toxoplasma myocarditis are reported, one of which presented and died due to massive pericardial effusion. All cases showed diffuse myocarditis with parasites on histopathological examination. Incidence of toxoplasma myocarditis in patients dying with AIDS was 8.3% (3 out of 36 cases).
