1/ Happy Tuesday, #medtwitter! It’s time to take that walk down the hall to radiology for another round of #readingroom - let’s go! 
2/ Looking at the previous tweet, where is the abnormal air located?
3/ If you said mediastinum, you’re right! This is also well characterized on chest CT pictured below.
Next question: how on earth did air get into the mediastinum? Reply with your thoughts, differentials and/or schema!

4/ The schema here is straightforward: one of the tubes that communicates with the outside and courses through the mediastinum must’ve ruptured.
5/ What you may not have known is that pneumomediastinum and pneumothorax often come together when the mechanism of action is alveolar distention and rupture. The CT below depicts this well.
6/ And that’s it for this week’s #readingroom! We hoped you learned a thing or two!
