I was diagnosed with a 3.4 arotic aneurysm in January of this year.  I realize that is relatively small, however, six months ago I had a CT scan with contrast and there was no mention of aneurysm.  So is that size any thing to be concerned about in six months time, or do they start about that size.

Summarized question: What could a 3.4 aortic aneurysm suggest?
