Isolated cardiac hydatid cyst: A rare but potentially life threatening presentation of hydatid infection.

Cardiac hydatid disease which is caused by the larval form of Echinococcus granuloses is the rarest yet significant presentation which is characterized by the formation of cystic lesions within the heart. It is not as common as hepatic, pulmonary hydatidosis, hence poses a unique diagnostic challenge. It may lead to severe complications like cardiac tamponade, embolism and arrhythmias.
