Overview

Imaging with chest x-rays remains as the gold standard of diagnosis when supported with other laboratory findings. Although x-rays provide reliable findings, it is recommended that the entire clinical picture along with supporting laboratory findings be taken into consideration before treatment is started. Patterns commonly found on imaging include lobar or focal nonsegmental pneumonia, lobular or multifocal bronchopneumonia, and diffuse or interstitial (atypical) pneumonia. Radiological findings may take 6-12 weeks to clear.

Lobar/ Focal non-segmental	Klebsiella pneumoniae Legionella pneumophila Haemophilus influenzae	Middle lobe pneumonia (Frontal) – Case courtesy of Dr Roberto Schubert Middle lobe pneumonia (Lateral) – Case courtesy of Dr Roberto Schubert Pneumococcal-pneumonia Right upper lobe – Case courtesy of Dr Jeremy Jones	Homogeneous (size may vary) opacification in a lobar pattern May be sharply defined at the fissures Appearance of air bronchograms
Lobular/ Multifocal Bronchopneumonia	Staphylococcus aureus Klebsiella pneumoniae Haemophilus influenzae Pseudomonas aeruginosa Escherichia coli	Bronchopneumonia (Frontal) – Case courtesy of Dr Henry Knipe Bronchopneumonia (Lateral) – Case courtesy of Dr Henry Knipe	Multiple small nodular opacities Patchy and confluent Patches of inflammation separated by normal lung parenchyma
Diffuse/ Interstitial (Atypical)	Mycoplasma Chlamydophila pneumoniae Chlamydophila psittaci Legionella	Legionella Pneumophilia – Case courtesy of Dr Jeremy Jones Chlamydia Pneumoniae – Case courtesy of Dr Andrew Dixon Mycoplasma – Case courtesy of Dr Alborz Jahangiri	Inflammation is limited to the pulmonary interstitium Patchy reticular or reticulonodular opacities Patches are more pronounced in the hilar regions Segmental atelectasis from small airway obstruction may occur Radiological findings are often more pronounced than the patients appearance
