Deep End

Since I'm on radiology, this week will be x-ray week.

This patient was brought into the emergency department due to trauma.

Challenge: What's the diagnosis? What kind of trauma did the patient sustain?

Deep End

This is the deep sulcus sign of a left sided pneumothorax. The costophrenic angle on the left side projects well below the costophrenic angle on the right side. This is due to accumulation of pleural gas in a subpulmonic location, outlining the anterior pleural reflection, the costophrenic sulcus, and the anterolateral border of the mediastinum. Also note that there is a bullet overlying the heart.
