subapical bronchopulmonary segment (left 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 left side, this segment sits:
- inferior to the apical segment
- posterior to the mid-portion of the oblique fissure
- superior to the anterior, lateral and medial basal segments
- superoanterior to the posterior basal bronchopulmonary segment
