Cardiac hydatid cysts with various myocardial locations. (A and B) 2D TTE, (C) contrast-enhanced thoracic CT scan, a multiseptated anechoic cyst located at the apex; (D) 3D TTE, a granulated spheric mass, with patchy hypoechoic regions located within the interventricular septum, (19, with permission); (E) CMR, hydatid cyst located within the interventricular septum with water content and a few daughter cysts; (F) gross examination of the surgically resected hydatid cyst; (G) SSFP cine (20, with permission) (H) CMR, showing left ventricular hydatid cyst with septations originating from the lateral wall into the left ventricular cavity (I) histological examination of the echinococcal lesion with cuticular membranes in cystic content, hematoxylin-eosin × 40.
2D TTE: two-dimensional transthoracic echocardiography; CT: computed tomography; 3D TTE: three-dimensional transthoracic echocardiography; CMR: cardiac magnetic resonance imaging; SSFP: steady state free processing.
