Is this my aortic arch?

Hi,

If anyone is willing to take a look at the picture here, It is the left side of my chest at the mediastinum which is being lifted. I think this is my aortic arch but not sure. Looks like a bulge to me. The ct showed left lung is larger and no mass or tumors which I wasn't concerned about. Something is making my chest grow under the rib at the mediastinum. Any help or clear information is appreciated.

This part of the anatomy is less clear to me than would an x-ray of bone.  Obviously a report should have been generated with the x-ray reading, has that given you any information?  I wish I could be more helpful.

Hi Eddie,

Thanks for taking a look. It hasn't given me anymore information. What is identified as my aortic arch is not this. You are very kind to take a look.
