Agenesis of the pericardium is a rare congenital anomaly, which is difficult to diagnose. We report a case of a 42-year-old patient, with atypical chest pain, electrocardiogram with an incomplete right bundle branch block, chest X-ray with a counterclockwise heart axis deviation and echocardiogram suggesting right ventricle volume overload. Cardiac catheterization showed no intracardiac shunts, and rotation and displacement of the heart into the left hemithorax. Magnetic nuclear resonance imaging confirmed the diagnosis by revealing partial absence of the left pericardium, with interposition of lung parenchyma between the main pulmonary artery and the aorta.
