Premature newborn with respiratory distress on a ventilator

CXR of a skin fold simulating a pneumothorax in a patient with respiratory distress syndrome
CXR AP shows diffuse symmetrical ground glass opacity throughout the lungs and a straight line running at an angle across the lower lateral left chest.

The diagnosis was a skin fold in the lower lateral left chest and not a pneumothorax in a patient with respiratory distress syndome.
