Morphology of the Superior Lobes of the Lung

Description

Cranial lung morphology is presented with emphasis on the superior lobes (lobus superior) of the right and left lungs, including the apical regions that rise above the level of the first rib. On the right, the superior lobe lies superior to the horizontal fissure and anterior to the oblique fissure, while on the left the superior lobe extends inferiorly into the lingula adjacent to the cardiac notch. Segmental contours are typically organized around the bronchopulmonary segments, with the apicoposterior and anterior segments on the left and apical, posterior, and anterior segments on the right forming the uppermost (cranial) lung silhouette. Spatial orientation. Upper-lobe anatomy matters because many clinical findings localize by segment and by fissure, not by whole lung, and the superior lobes behave differently in disease distribution and surgical planning than the lower lobes. Post-primary (reactivation) tuberculosis and apical bullous emphysema commonly involve the apical and posterior segments, and their proximity to the pleural cupola makes pneumothorax and pleural interventions more risk-relevant at the apex. For thoracic surgeons and interventional pulmonologists, accurate segmental mapping supports VATS segmentectomy, targeted bronchoscopy, and interpretation of lobar collapse patterns when a segmental bronchus obstructs. Use this artwork for teaching bronchopulmonary segments in gross anatomy, respiratory modules, and radiology correlation sessions where students must translate lobar and segmental terminology to CT and bronchoscopy reports. It also fits atlases, journal figures, and patient-facing education on upper-lobe resections, apical pathology, or lobar localization of lesions.
