Summary

Echinococcus infections of the liver and lungs are well-known, but cardiac echinococcus is rare, requiring further understanding. A 19-year-old male presented with chest pain, shortness of breath and palpitations. Changes in an electrocardiogram, increased troponin, and a computed tomography (CT) scan revealed a cardiac cyst at the left ventricle’s posterior lateral wall. Medical management included albendazole and praziquantel for 2 weeks followed by surgical cyst removal.

Clinical presentation of cardiac involvement of echinococcus granulosis is variable, requiring high clinical suspicion. Cardiac CT scan and echocardiography provided sufficient information for the diagnosis. The treatment included surgical removal of the cyst and albendazole administration.

Hydatid cyst is a rare zoonotic disease caused by the parasite Echinococcus granulosus [1]. The incidence in endemic areas is about 1–200 cases per 100,000 in population [2].

The liver (60–70% of cases) and lungs (20–30%) are the most common locations of hydatid cysts, with rare cardiac involvement of only 0.05% to 2% of all cases [3], with the left ventricle most frequently involved (60%) [2,4].
