 Brain MRI: Exam limited by motion.No restricted diffusion to indicate infarct. No susceptibility weighted abnormalities to indicate hemorrhage. No mass, mass effect or midline shift. The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. The pituitary gland is normal in size. There are no extraaxial fluid collections or subdural hematomas. The mastoid air cells are clear. Small amount of mucosal thickening in the posterior sphenoid sinus.Brain MRA: There is antegrade flow within the distal bilateral vertebral arteries, within the basilar artery, distal bilateral internal carotid arteries and carotid siphons and bilateral anterior, middle and posterior cerebral arteries. No arterial stenoses, occlusions or aneurysms are identified. No arteriovenous malformations are identified and there is no evidence for cerebral vasculitis. Neck MRA:Normal variant origin of the left common carotid artery off of the brachiocephalic trunk. No evidence for stenosis of the origin of the great vessels or of the bilateral vertebral arteries. There are no stenoses of the bilateral common, internal or external carotid arteries or of the bilateral carotid bifurcations. There is no evidence for vasculitis, fibromuscular dysplasia or dissection of the carotid or vertebral arterial systems within the neck. There are no vascular masses identified.
