Pneumothorax gallery

Normal reference

Use this chest x-ray as a normal reference for this gallery.

The lungs can be seen to reach the inner edge of the thoracic wall (arrows).

The two lungs meet in the middle at the posterior junctional line (arrowheads) and the anterior junctional line (not clearly visible). These normal lines, which consist of four layers of pleura (2 visceral and 2 parietal), are not always seen.
