Hydatid disease of the interventricular septum causing pulmonary dissemination.

Pulmonary dissemination of a cardiac cyst is a rare condition. In the present study, we report a case of a 20-year-old patient with cardiac hydatosis located in the interventricular septum, which was previously diagnosed and treated as pulmonary hydatid disease. Diagnosis was made by spiral computed tomography and treated surgically with median sternotomy and cardiopulmonary bypass. Diagnosis and proper surgical excision of the cardiac hydatid cyst prevented potentially lethal complications such as cyst rupture with recurrent pulmonary dissemination and anaphylaxis.
