title: Myocardial hydatid cyst ruptured into the pericardium: cross-sectional echocardiographic study and surgical treatment.
abstract: We describe a patient with a large intramyocardial hydatid cyst lying in the postero-lateral segment of the left ventricle near the atrioventricular groove level which ruptured into the pericardial sac, resulting in cardiac tamponade. Cross-sectional echocardiographic examination from a modified four-chamber apical view showed the multiloculated cyst and the breach connecting it to the pericardial sac, allowing for the definitive diagnosis and indication for emergency cardiac surgery. The risks of pericardiocentesis and invasive diagnostic procedures could thus be avoided.
