Lungs Phrenic never palsy and tracheal deviation!

Hey guys... does unilateral phrenic nerve palsy cause tracheal deviation? And if it does... is the deviation away from or toward the palsy?

Yeah, but I was thinking of trachea displacement because in phrenic nerve palsy the diaphragm to goes up, < lung filling --> atelectasis??? ---> tracheal deviation???

Nope... I don't think phrenic nerve palsy causes tracheal displacement. I haven't read from anywhere that it does... Phrenic nerve palsy is also never a differential diagnosis in tracheal displacement.

The diaphragm goes up but it doesn't cause compress the lung that much as to cause atelectasis or as to affect the trachea.

This is just what I think...

Thank you man... I was confused as I read that there will be athelectasis in phrenic never palsy, but is true... Differential Dx of tracheal displacement does not include phrenic n. palsy
