Pericarditis is a rare complication of amebiasis. A review of the literature revealed only 22 proved cases. The literature contains a number of reports of pericardial involvement in the course of hepatic abscess of probable, but not proved, amebic nature. Some of these cases occurred before the discovery of Endameba histolytica.
In a recent review amebic hepatitis and hepatic abscess were extensively discussed by Ochsner and DeBakey.1a These authors stated that various surveys of the population of the United States have shown the incidence of amebiasis to be between 5 and 20 per cent. The incidence of associated hepatitis and hepatic abscess varies considerably in different statistical analyses. As was pointed out by Ochsner and DeBakey, this incidence is significantly higher in the cases in which autopsies were performed than in the clinically observed cases. These authors collected a series of 5,211 fatal cases of amebiasis and noted that
