The arrows identify a number of pneumothorax-like appearances.
Right Lung
Lung markings are seen to extend beyond the arrowed structures suggesting that these appearances are associated with skinfolds.
Left Lung
The bottom arrow identifies a curvi-linear structure that extends inferiorly beyond the lateral chest wall. This represents a skinfold.
The other curvilinear structures are also skin folds
Important Clues
- This is an elderly lady who is likely to have loose skin that has a propensity to fold/wrinkle/pucker producing skinfold artifacts.
- The chest soft tissue skin-lines laterally, particularly on the left, suggest loose skin.
- The radiography was performed with the patient in a sitting position resting against a hard cassette- this position/technique is notorious for producing skin folds that mimic a pneumothorax.
- Bilateral pneumothorax does not fit with the clinical picture.
