What’s the Diagnosis #6

A 39 year old male with a 1 pack per day smoking habit presents with acute onset of shortness of breath and right-sided chest pain. You obtain an x-ray that is shown below. What is the diagnosis?

CXR

If you said “pneumothorax”, you’re right.
You decompress the pneumothorax using a Cook catheter and Heimlich valve. You hear a rush of air through the needle as the patient breathes out. You obtain a second chest x-ray to confirm that the lung is re-expanded. The result is shown below. Now what is your diagnosis?

Bullous Emphysema with Pneumothorax
When I initially saw the second x-ray, I was going to put in a second chest tube, suspecting that part of the pneumothorax had become walled off or loculated. Then I saw small septations in the right lung field and conferred with the radiologist who agreed that there was no further pneumothorax present.

Absence of lung tissue is noted in the right lower lung field in the first x-ray.
In the second chest x-ray, a small catheter can be seen in the right lateral 5th interspace. The remaining lung tissue is expanded, but multiple large bullae remain in the upper lung field, simulating a persistent pneumothorax.

    My diagnosis was “whoa, that dude has fuzzy white stuff all up in his lungs. that can’t be good.”

    Isn’t he a bit young for emphysema? I’d look for underlying causes.
