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.
There are a number of potential mimics for a pneumothorax. Perhaps the most common is a skin fold. These typically occur in:
- The elderly with loose skin as a result of ageing.
- On an AP film
The appearances can catch the untrained eye - be sure to review the lucency / presence of lung markings peripherally.
