subapical bronchopulmonary segment (right inferior lobe)
Last reviewed 01/2018
In roughly half of the population, directly inferior to the apical segment of the inferior lobe of the lung is a subapical bronchopulmonary segment. It is supplied by a separate subapical segmental bronchus derived from the inferior lobe bronchus.
On the right side, the segment sits:
- inferior to the apical segment
- posterior to the inferior portion of the oblique fissure
- superior to the medial basal and posterior basal segments of the inferior lobe
- lateral to the lateral basal bronchopulmonary segment
