Could a past vertebral artery aneurism(?) present as a cyst on a cspine mri (without contrast) at c6-7?

Ask radiologist: This may be a legitimate question to ask the radiologist who viewed your mri. You should make sure that he is aware of your medical history when he takes a second look at the mri. He may also suggest that you do a ct angiogram or a mra study (rather than a non contrast mri) to specifically key in on the blood vessels of that region.
