Unilateral focal or patchy consolidations in dependent lung segments
Right lower lobe is most common area; bilateral patterns can also be seen
Lower lobe infiltrate when<unk>  occurs in upright position
Upper lobe infiltrate when<unk>  occurs in recumbent position
CT
Increased sensitivity, specificity, and overall accuracy compared to CXR
Reasonable to obtain even if CXR negative if clinical suspicion is high<unk>  is a risk factor for pulmonary abscess formation
