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
