title: Atypically located pericardial cyst compressing the left ventricle during the whole cardiac cycle: a case report.
abstract: We report the uncommon case of a pericardial cyst with unremitting compression of the left ventricle during the whole cardiac cycle, but normal ejection fraction. On CT scan, the cyst was found at an atypical location, lateral to the pulmonary artery, the ascending aorta, and the right ventricular outflow tract in the left anterior mediastinum. The radio-density of the cyst was 41 Hounsfield units (HU), higher than other cases reported in the literature. As the cyst was stable, conservative treatment was adopted. The usefulness of echocardiography for the diagnosis and follow-up of pericardial cysts is discussed.
