If so, did it cause you any problems or did you do anything to try to resolve it? Were you told anything about the cause?
I just noticed that this is on my chest CT report from mid-October. Two doctors (my onc and the urologist who ordered the CT) have seen the report and neither of them commented on it at all. I see that surgery can be a precipitating factor but there was no mention of it on my CT report from this summer, and my most recent surgery (port placement) was all the way back in February.
