Main Pulmonary Artery Hydatidosis with Seconday Involvement of the Lungs: a Shepherd Boy’s Story

Abstract

Cardiac hydatid cyst (CHC) is a rare disease that was endemic in some regions especially in sheep-raising areas. The most commonly accepted theory for the routes of heart involvement in hydatid cyst was infestation by the hexacanthus embryo through coronary arteries. Here, we describe a case with the primitive cardiac hydatid cyst located around the pulmonary valve (PV) and main pulmonary artery (mPA) extended to right and left pulmonary arteries and metastasized to both lungs. Could it be possible for the embryo to adhere PV and mPA directly?
