title: CT findings in hemitruncus.
abstract: Origin of the right pulmonary artery from the ascending aorta is a rare congenital malformation resulting in a large left-to-right shunt through the right lung at systemic pressure. We report the CT findings in an adult with this anomaly. Computed tomography was diagnostic. The patient is the sixth adult with this condition reported in the literature.
