Left upper lobe apicoposterior segment

The left upper lobe apicoposterior segment is one of the bronchopulmonary segments of the left upper lobe. As its name suggests, it is the most apical and posterior of the segments within the left upper lobe and is supplied by the left apicoposterior segmental bronchus.

It is the equivalent segment to a merger of the apical and posterior segments of the right upper lobe.
