PNO Figures 2

Oblique lateral. There is a knife projected through the right scapula between the

posterolateral right third and fourth ribs extending into the right thorax with an

associated large pneumothorax.

Decubitus. There is a knife projected through the right scapula between the posterolateral right

third and fourth ribs extending into the right thorax with an associated large pneumothorax.

Large right pneumothorax. Small pleural effusion.

After expiration. Large right pneumothorax. Small pleural effusion.

Right pneumothorax. Pleural reflection indicated by the arrows.

Page 6: Medical Imaging of Pneumothorax (PNO)–FIGURES 2-Walif Chbeir

Large left sided pneumothorax (7 cm at level of left hilum) with collapse of left lung

structures. Some mediastinal divergence from midline - possible tension pneumothorax. Right

lung clear.

Pneumothorax mimic - skin fold. Linear abnormality nearly parallel to the right chest wall

extending from base to apex. Lung marks are evident peripheral to this line, implying this is not

air in the pleural space.

Tension PNO. Chest x-ray demonstrates a large left sided pneumothorax. The lung is almost

completely collapsed, and there is shift of the mediastinum towards the right.

Tension pneumothorax mimic due to right lower lobe hypoplasia. Fig1. Left pneumothorax.

Mediastinal shift towards right, depression of left hemidiaphragm, concerning for tension

pneumothorax.

Chest radiograph prior to pacemaker insertion (previous day). Rightward mediastinal shift.

Defibrillation pad noted. No pneumothorax. Comparison radiographs - previous day (with

defibrillator pad) and 10 years previous

Right sided pneumothorax with pleural line seen laterally and well-defined right

hemidiaphragm. Differences in opacity between the right and left hemithorax are exacerbated

by grid cut-off artefact.

Page 14: Medical Imaging of Pneumothorax (PNO)–FIGURES 2-Walif Chbeir

Subcutaneous emphysema is seen in the right lower chest wall along with rib fractures of 4th to

6th right lateral rib fractures. The right hemidiaphragm has a crisp outline which is suggestive

of a pneumothorax. Right upper zone consolidation. The left lung is clear. Cardiomediastinal

contour is within normal limits for the projection.

indicating significant tension. ETT is in a satisfactory position.

Loculated pneumothorax due to pleural adhesions. Apical lung bullae or blebs that

predispose to spontaneous pneiumothorax. These blebs are not on the background of bullous

emphysema.
