A 75-yr-old farmer from Parsabad-Moghan, northwestern Iran was presented to the Emergency Room of Tehran Imam Khomeini Hospital, Tehran, Iran with dyspnea and without chest pain in 2014. A lesion compatible with hydatid cyst was found in echocardiography and confirmed by serology and MRI. Surgical treatment was done but the patient was died in recovery room because of cardiac arrhythmia. In endemic areas, hydatid cyst should be considered in differential diagnosis of heterogeneous echogenic lesions even if the serologic tests are negative. Physician can use cardiac MRI to earn valuable information about the lesion and its relation to other structures. However, with all of these assessments, surgical removal of cardiac cysts may have some complications.   https://ijph.tums.ac.ir/index.php/ijph/article/view/8354 https://ijph.tums.ac.ir/index.php/ijph/article/download/8354/5377
