Medial stripe sign

Last revised by Daniel J Bell on 7 Jan 2020

The medial stripe sign refers to an area of increased lucency at the interface of the medial lung and the mediastinum on a chest radiograph in a case of medial pneumothorax. A small pneumothorax generally accumulates anteriorly or medially which may be difficult to detect, hence this sign holds a certain significance.
