 As noted on the prior MRI orbits, there is stable asymmetric prominence of the lateral aspect of the ophthalmic segment of the left internal carotid artery, with a small area of outpouching measuring 4 mm AP x 2 mm transverse. Comparing back to the CT neck with contrast from October 2014, this is grossly similar.The intracranial internal carotid arteries are otherwise normal in course and caliber. The middle and anterior cerebral arteries are unremarkable. The vertebral arteries, basilar artery, and posterior cerebral arteries are normal in course and caliber. There is no evidence of flow-limiting stenosis or other suspected aneurysm.
Area of focal prominence along the lateral aspect of the ophthalmic segment of the left internal carotid artery which may represent a small aneurysm measuring 2 x 4 mm versus an area of focal atherosclerotic related ectasia of the vessel, although could be better characterized on CTA of the head.
