Constrictive pericarditis due to hepatopericardial fistulas of hepatic echinococcosis

Hydatidosis is a parasitic infestation which is endemic to sheepherding regions of the world. Constrictive pericarditis secondary to pericardial hydatid disease is a very rare dentity. In our case, the cyst was not a primary cardiac hydatid cyst. In this article, we report a 72-year-old male case of constrictive pericarditis due to fistulization of a hepatic hydatic cyst to the pericardium. Partial pericardiectomy and drainage of the hepatic cyst were performed successfully, followed by medical treatment.
