Toxoplasma pericarditis in acquired immunodeficiency syndrome.

Large pericardial effusions are now a well-known complication of the acquired immunodeficiency syndrome, mainly caused by mycobacterial disease. However, other etiologies can be found. We report a case of toxoplasma pericarditis without other parasitic localizations. Pericarditis is a very uncommon clinical feature during toxoplasmosis. Its diagnosis is often difficult to establish, particularly in immunocompromised patients. Nevertheless, its possible evolution to constriction or tamponade requires its consideration. New methods of rapid tissue cultures may be helpful and allow early specific treatment.
