Sepsis of unknown source. To exclude pneumonia.

Patient Data

Age: 70 years
Gender: Male

AP Chest Radiograph


Normal cardiomediastinal contours. The lungs are clear with no focal collapse or consolidation. No pleural effusion. No pneumothorax. Bilateral skinfolds noted.

Case Discussion

Skinfold artifact can give a false appearance of a pneumothorax. In this case, the following features help to distinguish a skinfold artifact from a pneumothorax:

  • the skinfolds do not follow the expected course of pleura in a pneumothorax
  • the presence of vascular lung markings extending beyond the skinfold margin
