Cardiac Hydatid Cyst in a 34-Year-Old Ethiopian Woman With Heart Failure.

Although the majority of hydatid cysts are found in the liver and lungs, cardiac hydatid cysts, particularly those in the left ventricle and interventricular septum, pose unique challenges because of their extremely rare manifestation of cystic echinococcosis, critical location, and potential for serious complications. Although uncommon, a hydatic cyst of the heart should be investigated in a patient with an intracardiac mass-particularly if it is cystic-and in a patient with symptoms of heart failure caused by a mass shown in imaging examinations. We present a case of left ventricular hydatid cyst in a 34-year-old woman who had been complaining of worsening dyspnea, shortness of breath, orthopnea, and cough for 3 weeks.
