7/ o m presents to the ED after coughing while playing with legos. He is satting 100% on room air, comfortbale playing in the room. His CXR shows:
"There is no acute cardiopulmonary process. there is no evidence for
radiopaque foreign body. There is no significant evidence for air-trapping."
No evidence for air-trapping
We take a look at the CXR ourselves, do you see anything pecuilar? (CLICK ON XRAY its a thumbnail)
Look at the right mainstem area, can you make out the pinholes of a lego piece? Apparently there is no air trapping because the lego was not solid but had a hole in the middle of it!
It helps that he had unilateal wheezing on that side and stridor, but either way a piece of lego was removed form his right mainstem bronchus.
