Cardiac hydatid disease: CT and MRI findings.

The purpose of this article is to review the CT and MRI findings of cardiac hydatid disease. CT and MRI are helpful for localizing and defining the morphologic features of hydatid cysts. Specific signs include calcification of the cyst wall, presence of daughter cysts, and membrane detachment. CT best shows wall calcification, whereas MRI depicts the exact anatomic location and nature of the internal and external structures.
