Cardiac hydatid cyst

Statistics from

Hydatid disease is a parasitic infestation caused by larvae of the echinococcus tapeworm. Cardiac hydatid cyst is uncommon, and we report a case involving a 30 year old woman who had experienced a single syncopal episode. Echocardiography showed a large multivesicle

cyst in the ventricular cavity. The cyst, measuring 6 × 4 × 5 cm, was localised in the inferoposterior wall of the left ventricle. Thoracic computerised tomography (CT) and magnetic resonance imaging (MRI) also revealed a hypodense mass in the left ventricular cavity. A diagnosis of primary cardiac hydatid cyst was confirmed and total cystectomy was performed.  Echocardiography is the best diagnostic procedure for cardiac hydatid disease, although thoracic MRI and CT, and abdominal CT, are also necessary for detecting the exact location, size and number of disseminated hydatid cysts.
