ABSTRACT
Hydatid cyst disease is a significant health problem for undeveloped and developing countries. Humans are infected by way of contaminated dogs or contaminated uncooked vegetables. Cardiac hydatid cyst disease is uncommon, occurring in approximately 0.5% to 2% of patients with hydatid disease. Most cardiac hydatid cysts are located in the left ventricle and interventricular septum. The rate of pericardial hydatid cysts is (2-10) % of cardiac echinococcosis. Although cardiac involvement is rare, early diagnosis and treatment of this situation is important. Surgical options include sternotomy, thoractomy and video assisted thoracoscopy (VATS). In the present report, a 17-year-old girl with pericardial and hepatic hydatid cyst is described and it has been treated with left VATS for pericardial cyst. In the present patient, the hydatid cyst was located inside the pericardial cavity without myocardial involvement.
