Cardiac involvement in hydatid disease is uncommon, and account about 0.5 to 2% of hydatidosis. The left ventricle is the most common location (about 60%) and the pericardium about 10% of cases. The symptoms are variable directly related to the size and location of the cysts.

Both CT and MRI are helpful to precise the morphological features of the cysts as well as their location. CT is the best modality in the detection of the wall calcification, whereas MRI  depicts better the anatomical location as well as the internal and external components of the cysts. Surgery is the treatment of choice
