Quiste hidatídico en ventrículo derecho

Abstract

A 20-year-old woman, without known pre-existent conditions presented with a history of dyspnea on exertion, and palpitations for 6 months. Vital signs, as well as cardiac and pulmonary examinations were normal. Routine blood tests were normal. The ECG showed nonspecific ST-T changes. The echocardiogram showed a left ventricle of normal size and function. A cystic image was shown in relation to the right ventricle, with displacement of the interventricular septum. These findings were confirmed on computed tomography. Additional cystic images on the liver or lungs were ruled out. On surgery, a cardiac hydatic cyst adhered to the pericardium next to the right ventricle was found. Puncture, drainage of the mass and surgical removal of cystic membranes were performed. The clinical course was uneventful. A four year follow up revealed no recurrence of the cyst.
