Amebic pericardial effusion: a rare complication of amebic liver abscess.

Two rare cases of amebic pericardial effusion as a complication of amoebic liver abscess in the left lobe are described. The pericardial amebiasis should be suspected in a patient presenting with signs and symptoms of pericardial effusion with an evidence of hepatic abscess (in the left lobe) or in a patient with pericardial effusion of uncertain etiology. Aspiration of "anchovy sauce" pus from both the pericardial cavity and the liver should be regarded as confirming the diagnosis of amebic pericarditis secondary to amebic liver abcess because demonstration of Entamoeba hystolytica is seldom possible. Removal of pericardial pus and metronidazole intake were markedly effective in treating our patients.
