Aberrant ramuts of left pulmonaly artery to inferior lingular and anterior basal segment (A⁵⁺⁸)

Abstract

A 68-year-old man underwent radical left lower lobectomy for adenocarcinoma in segments S⁶ and S¹⁰. Aberrant ramification of the left pulmonary artery was recognized. This artery, running along the anterior aspect of the lower lobe bronchus, had two rami into the inferior lingular and the anterior basal segments (A⁵⁺⁸), and it branched off the root of the left main pulmonary artery. This may be an embryological variation of the pulmonary artery and left eparterial bronchus, a congenital abnormality.
