Abstract

Aberrant origins of the pulmonary artery are rare anomalies, but are being reported several times in the world literature. Among them, pulmonary artery sling is the most well known anomaly, which is the left pulmonary artery arising from the right pulmonary artery. In case of pulmonary artery sling, the left pulmonary artery causes compression of the trachea and esophagus while it courses inbetween. In this case, we describe a case on incidentally found aberrant origin of the upper left lobe anterior and superior lingular segmental pulmonary artery without any compressions of the esophagus or trachea. In the world literature, aberrant origins of the left pulmonary artery without pulmonary artery sling was reported at one time, but currently, this is the first case of aberrant origin of the upper left lobe anterior and superior lingular segmental pulmonary artery arising from the right pulmonary artery.

  Fig. 1 Multislice CT axial image (A) and 3D volume rendering image (B) showing abnormal origin of a single stem of artery from posterior aspect of the right pulmonary artery (black arrow). It divides into two branches and distributes in left upper lobe anterior segment (white arrow) and superior lingular segment (open arrow).
