Recurrent apical cardiac hydatid cyst presenting with angina.

Hydatid disease is a parasitic infection caused by the larvae of tapeworm Echinococcus Granulosus. Hydatid cyst of the heart is an uncommon presentation of human echinococcosis which may lead to life-threatening conditions. We present a rare case of recurrent pericardial cyst in a 42-year-old man presenting with chest pain and ECG findings. We were able to avoid risks of resternotomy with a limited anterolateral thoracotomy. A direct enucleation of the cyst was possible without the need for cardiopulmonary bypass. He was free of complications at 6-month follow-up. Diagnosis should be suspected in every case of anginal symptoms or cyst-like mass in persons coming from areas where echinococcus granulosus is endemic.
