 Images are limited by patient motion. The intracranial internal carotid arteries are normal in course and caliber. There is a hypoplastic right A1 segment. The middle and anterior cerebral arteries are otherwise unremarkable. Right vertebral artery is slightly dominant. The vertebral arteries, basilar artery, and posterior cerebral arteries are normal in course and caliber. There is no evidence of flow-limiting stenosis or aneurysm.MRA NECK
1.Significantly motion limited exam. Findings suggestive of subtle asymmetric enhancement of the right geniculate ganglion and possibly the proximal right tympanic segment of the facial nerve. Questioned focus of enhancement in right Meckel's cave along the trigeminal nerve. No significant inner ear or cranial nerve VIII abnormality is appreciated. Findings could represent mild inflammatory changes such as a focal neuritis.2.Mild dural thickening and enhancement persists along the right internal auditory canal walls which may be reactive in etiology. No focal mass identified.3.Motion limited MRA, although grossly unremarkable.
