Abstract
The human lungs, situated in the thoracic cavity, are divided into lobes by fissures. The right lung consists of three lobes, which are separated by both oblique and transverse fissures, while the left lung has two lobes, divided by the oblique fissure. Recognizing these anatomical differences is essential for clinicians, as it aids in procedures such as lobectomy and enhances the accuracy of radiologic interpretations. We present a case of complete absence of the fissure in the left lung of a male cadaver, observed during routine thoracic dissection in the Department of Anatomy, King George’s Medical University, Lucknow, UP. The left lung displayed a rare absence of the oblique fissure, resulting in a smooth, convex costal surface. Typically located along the midaxillary line and posterior border, the oblique fissure was notably absent. However, the structures in the hilum and the impressions on the medial surface appeared normal, with no other fissural abnormalities. A clear understanding of lung fissure patterns is essential for radiologists, as it helps in accurately diagnosing lung pathologies without confusion. In cases where a fissure is absent, lobar pneumonia, which is typically confined to a specific lobe, may spread throughout the entire lung. Clinicians and surgeons should be mindful of such anatomical variations when treating patients and assessing the prognosis of lung diseases.
