Case Discussion

The deep sulcus sign was originally attributed to the classic supine chest x-ray projection.

In this case the patient was mobile and the x-ray is erect. The air under the lung gives rise to the "deep sulcus". It's a handy way to catch your eye and draw attention to the subtle pneumothorax.
