Chest X-Rays

Lobar Pneumonia

Extensive consolidation with branching radiolucencies corresponding to bronchi (air bronchogram sign) of the right lung. Obscured right hemidiaphragm suggests right lower lobe involvement (silhouette sign). Image Courtesy of Radiopaedia and Copylefted.

Consolidation of the right middle lobe. Air bronchogram sign is modestly evident. Image Courtesy of Wikimedia Commons and Copylefted.

Right upper lobe consolidation with air bronchograms. Features of pneumonia.

Notice that the left heart margin remains distinct - helping distinguish upper from lower lobe pneumonia.

Interstitial Pneumonia

Infiltration of the right middle lobe.

Ground-glass pattern is seen on the X-ray.

Atypical pneumonia has the radiographic features of patchy reticular opacities.

Curved red line shows a bulging fissure which is typical for Pseudomonas, Staphylococcus aureus,Klebsiella pneumoniae

Multifocal patchy air space opacification without a zonal predilection.

Right hemithorax air space shadowing predominantly right sided signs were correlated with this radiograph with almost complete right sided air space opacification and early left basal changes.

Chlamydia pneumonia before treatment.

Chlamydia pneumonia one month later

Right hilar mass (orange) obstructing the right upper lobe bronchus results in collapse of the right upper lobe (green arrow). This results in a reverse S shape to the pleural edge. .

x400px|thumb|The right hemidiaphragm is elevated with some minor right basal atelectasis. Hazy airspace opacity is seen in the left mid and upper zone which may be inflammatory in nature. No areas of confluent consolidation are identified.

CT Images

Pneumonia with abscesses on both lungs, caverns on the left lung and effusions on both lungs.

Right sided pneumonia.
