Hydatid disease is a human infection caused by the larval stage of Echinococcocus granulosus, which is still endemic in many cattle-raising areas. Cardiac hydatid cysts are very rare, involving 0.5 to 2% of all cases. but potentially a very serious complication of the hydatid disease. The diagnosis of cardiac cyst hydatid may be difficult due to the nonspecific symptoms and varying clinical presentations. A 46-year old man who had a known previous history of hepatic cyst hydatid was admitted to our clinic because of progressive dyspnea, atypical chest pain and fatigue for two weeks. On physical examination, his respiratory rate was 18/min; heart rate was 112 beats/min and blood pressure was 110/70 mmHg. Electrocardiography showed sinüs tachycardia. Transthoracic echocardiography (TTE) revealed multiple intracardiac and pericardial unilocular cystic spheric hyperechogenic masses with well-defined margins (Figure-1 and 2). A contrast-enhanced computed tomography (CT) showed two cyst in the left and right atrium and multiple cyst in pericardium and a cyst in left ventricle posterior wall (Figure-3 and 4). On the basis of these findings, the patients was referred cardiac surgery but he refused and has been followed up medically under albendazole treatment. Herein, we report a case of a pan cardiac hydatid cyst. The diagnosis was established by TTE and CT Scan. This case illustrates the diagnostic value of the non invasive imaging means in hydatic cyst of the heart.
