Incomplete Transverse Pulmonary Fissures: Embryological Basis, Clinical, and Surgical Implications: A Cadaveric Case Report

Incomplete pulmonary fissures (IPF) represent a common anatomical variation in the human lung. While often considered silent, incomplete pulmonary fissures can have notable clinical and surgical implications, necessitating a comprehensive understanding of their anatomical characteristics. IPF may have significant implications in both clinical practice and surgical interventions. We report a case of an incomplete transverse fissure of the right lung from an adult male cadaver, exploring the embryological basis, clinical significance, and surgical implications. The findings underscore the importance of understanding the lung embryology and resulting normal anatomy, and associated anatomical variations to ensure accurate diagnosis, appropriate management, and optimal surgical outcomes.
