Organ
Right inferior lobe
Posterior and basal right lung lobe
High-yield
One superior segment and four named basal segments give the usual five-segment pattern.
Overview
The inferior lobe extends behind the oblique fissure and across much of the right lung base. Its superior segment rises posteriorly above the basal group.
Reference facts
- Location
- Posteroinferior right lung, adjacent to the diaphragm
- Parts
- Superior S6; medial basal S7; anterior basal S8; lateral basal S9; posterior basal S10
- Blood supply
- Inferior lobar branches of the right pulmonary artery
- Innervation
- Right pulmonary plexus
- Relations
- Posterior thoracic wall and right diaphragm; liver lies below the diaphragm
- Function
- Gas exchange in the posterior and basal right lung
Clinical correlation
The posterior position means disease here may be less apparent from an anterior examination. A lower-lobe opacity touching the diaphragm can obscure that border on a radiograph.
