Persistent Truncus Arteriosus is a cyanotic congenital heart anomaly in which a single trunk supplies both the pulmonary and systemic circulation, instead of a separate aorta and a pulmonary trunk. It is usually classified as a conotruncal anomaly. Due to parallel fetal circulation, truncus arteriosus does not cause any haemodynamic problem in utero. However it is a major problem postnatally and, if left untreated, approximately 80% of infants die within the first year. Diagnosis should be made early by radiologists and cardiologists due to fatal illness. We found it valuable to present a case of truncus arteriosus with computerized tomography findings because of its rare occurrence.
Fig. 1 It was observed that the cardiomegaly, and aorta and the pulmonary trunk were in the middle trunk.
Fig. 2 The trunk emerged from the right ventricle and a VSD of 5 mm diameter was observed.
Fig. 3 Secundum type ASD was observed in the interatrial septum.
Fig. 4 Patent ductus arteriosus is observed in the sagittal reformat images.
Fig. 5 PTA is observed in 3D Volume Rendering images.
