Question:
What does "prominent aortic knob" mean?
During a skeletal survey for multiple myeloma, the radiologist observed a "prominent aortic knob". Have not yet seen my doctor. What is this, and how dangerous? I am a 70 year old female with family history of aortic dissection.

A prominent aortic knob signifies that the aorta is slightly elongated. In some instances, it may indicate an aneurysm, but more often than not, it is unimportant. I am not aware of any substantive relationship between multiple myeloma and a prominent aortic knob.
