What Does It Mean Subtle Broad Basedvascular Fullness Arising From

what does it mean subtle broad basedvascular fullness arising from the medial surface of the ophthalmic segment of the left ica. 2 mm blister aneurysm versus ulcerated atheroscierotic plaque. I had this mri done a couple of years ago. I am reading the report now only because I keep getting dizzy it only last for a couple of seconds but it is constent. I am a little nervous but have not seen a doctor yet, the dizziness started a couple of weeks ago.. thank you Darlene
