I would put my money on a ruptured trachea/main bronchus.
I have absolutely no idea if its correct and Im answering using this strategy:

Tension pneumothorax wouldnt cause a subcutaneous emphysema.

Rupture of trachea/main bronchus because she has pneumothorax (Pneumothorax occurs when a part of airway is ruptured and air is filled in space between the 2 pleura). Which means she has probably ruptured some part of her airway and this tear/rupture must have continued upwards to the trachea/main bronchus. (I know it doesn't sound convincing but its the best I could come up with.)

Well i guess they might be using the logic as follows:
Too much air in pleural space due to tension pneumothorax which ruptured the pleura due to immense pressure and caused subQ emphysema..
