🚨 This CXR shows a large pneumothorax with possible mild tension🫁💥

One of the most dangerous “simple” diagnoses in imaging—because missing it changes everything.

🧠 How to never miss a pneumothorax again:
➡️Pleura is a pencil-thin white line with air (black) on either side
➡️Lung markings will be absent more peripherally
➡️Invert the image for improved visualization
➡️Helpful if deep sulcus sign is present on supine view

🕵️‍♀️Watch out for the fake-outs like skin folds!

📞☎️Instant, no-hesitation phone call needed!
