Polycystic disease of the kidneys complicating the diagnosis of myocardial echinococcosis.

Abstract

The case of a 30-year-old woman with polycystic disease of the kidneys and a large cyst in the interventricular septum is presented. The hypothesis of an echinococcal disease or of a cardiac manifestation of a polycystic disease was raised. The patient's history, serologic data, and the morphological aspect of the cyst did not give evidence for echinococcal disease before surgery. However, the postoperative pathological evaluation confirmed the diagnosis of a single echinococcal cyst. The presented case shows that even in cases without proven diagnosis of echinococcal disease and preexisting hereditary cysts in other organ systems, care should be taken during surgery to avoid anaphylaxis and preoperative spread of the parasite throughout the body.
