Some calcification of the arteries is actually considered fairly normal in the aging process. However, this can also be a sign of impending problems (just like your Marine Corps doc mentioned years earlier). A couple of things - are you or have you ever been on warafarin, or taking anything for the treatment of osteoporosis (including calcium supplements or antacids)? Did they do a complete upper body CT scan or just scan your pelvis/groin? You may want to ask for an abdominal and aortic CT scan just to be sure that you don't have more in those areas. Vitamin K will help the body synthesize the calcium by reabsorbing it and help to prevent more from forming.

Did they indicate to you any need for alarm or just point it out as an incidental finding?

I do hope that it isn't anything to worry about,

PS., are they referring you to a vascular surgeon for further evaluation? I would recommend seeking an opinion from a vascular specialist!!
