Cardiac hydatid cyst associated with multiple organ involvement

A 5-year-old boy was admitted to the hospital with recurrent cough and chest pain for 2 months. Chest x-ray demonstrated multiple round opacities and abdominal tomography revealed two cyst formations in the liver and another one in the spleen. The boy had no cardiovascular symptoms, but transthoracic echocardiography (TTE) was carried out to explore nonspecific T-wave alterations on the electrocardiogram. TTE revealed a single cyst in the posterior wall of the left ventricle. Hydatid disease is a serious worldwide cestode but, echinococcal involvement of the heart is uncommon.
