Right lower lobe consolidation

Dr Craig Hacking and Dr Jeremy Jones et al.

Right lower lobe consolidation refers to consolidation in part (incomplete) or all (complete) of the right lower lobe.

Consolidation refers to the alveolar airspaces being filled with fluid (exudate/transudate/blood), cells (inflammatory), tissue, or other material.

The list of causes of consolidation is broad and includes:

Consolidation is usually obvious on CT, however features can be more subtle on chest radiography. Features of right lower lobe consolidation on CXR include:

It must be remembered that the homogeneity of the consolidation will be influenced by any underlying lung disease.

Occasionally with complete lobar consolidation, there may be an increased volume of the affected lobe, rather than the more frequent collapse. When the fissures are outwardly convex, the appearance is referred to as the bulging fissure sign.

A mnemonic to remember the general features of consolidation is A2BC3.
