The Anomalous Lobar Pattern Of Left Lung: A Case Report

Abstract

The left lung classically has one fissure, an oblique fissure; dividing the organ into separate upper and lower lobes which are connected only by lobar bronchi and vessels. The anomaly of the lobar pattern has been described by some research workers on radiographs and fewer studies on gross anatomical specimen. In this present case, an incidental finding in the gross dissecting lab; we report two fissures in the left lung dividing it into three lobes: a right pulmonary isomerism. Knowledge of this fissure variant is important for surgeons and radiologist and might be useful in interpreting unusual forms of atelectasis or consolidation occurring adjacent to the fissure.
