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.

the case <a href="https://radiopaedia.org/cases/18975">rID: 18975</a>
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.

case <a href="https://radiopaedia.org/cases/37132">rID: 37132</a>
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.

<a href="https://radiopaedia.org/cases/26496">rID: 26496</a>
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

<a href="https://radiopaedia.org/cases/10970">rID: 10970</a>
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

A pneumothorax in a supine patient demonstrated by deep sulcus sign on the right.

case <a href="https://radiopaedia.org/cases/13262">rID: 13262</a>
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.

case <a href="https://radiopaedia.org/cases/27794">rID: 27794</a>
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.

case <a href="https://radiopaedia.org/cases/31381">rID: 31381</a>
Supine tension pneumothorax. Large right pneumothorax with mediastinal shift to the left
indicating significant tension. ETT is in a satisfactory position.

case <a href="https://radiopaedia.org/cases/39435">rID: 39435</a>
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.
