I have been having shortness of breath for a couple weeks now and just went to see a pulmonologist which he stated one of my levels were a little below average but everything else on the Pulmonary Function Test was normal. He looked at my chest xrays and noticed that my pulmonary artery looked a little larger. I am a very small framed person. I am a little under five feet tall and around 85 lbs. This has been my average weight for as long as I can remember.
Anyways, my question is because I am a small framed person (according to the pulmonologist my chest wall is thin), can my pulmonary arteries show up a little bigger because of my frame? What types of diseases other than pulmonary hypertension could cause this?
Thanks
