Echocardiography demonstrated a round echolucent well-defined mass (47 × 25 mm) on the base and the mid lateral wall of the left ventricle (LV) without septation.

Coronary angiography showed upward displacement in the LAD with significant compressive narrowing. The patient underwent mass resection and grafting of the LAD. During surgery after the incision of the pericardium, the hydatid cyst entity of the mass was revealed. Hydatid cysts covered the anterolateral surface of the LV with adhesion to the pericardium. The patient recovered from the surgery uneventfully. Pathology report and immun...Continue Reading
