The left lower lobe superior or apical segment is one of the four bronchopulmonary segments of the left lower lobe. It is the most apical of the segments in the left lower lobe, posterior to the upper aspect of the oblique fissure and apicoposterior segment of the left upper lobe.
Due to its high position, pathology in the left lower lobe superior segment can produce mid to upper zone opacification on chest radiographs.
