 MRI Brain:There is thin T1 and T2/FLAIR hyperintense fluid signal along the right anterior inferior frontal lobe, and along the left occipital lobe. These collections measure no more than 2 to 3 mm in thickness and exerts no significant mass effect upon the adjacent brain parenchyma. There is no evidence of mass, or acute infarct. The brain parenchyma and pituitary gland otherwise appear unremarkable. No pathologic enhancement is seen. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is a small residual right periorbital hematoma.MRA Brain: The intracranial internal carotid arteries demonstrate no significant stenosis. The middle and anterior cerebral arteries are also patent. Small P-comm arteries are present. There may be a small fenestration of the vertebrobasilar junction which is a normal variant. The vertebral arteries, basilar artery, and posterior cerebral arteries also are patent with no significant stenosis. No evidence of aneurysms or vascular malformations.MRA Neck: There is a separate origin of the left subclavian artery, left common carotid artery, and brachiocephalic artery from the arch. The common carotid arteries and cervical internal carotid arteries are normal in course and caliber. There is no evidence of stenosis or occlusion. The origins of the vertebral arteries are patent. However, the V2 and V3 segments are not well assessed bilaterally secondary to field-of-view limitations.
1. Trace subdural hemorrhage along the right frontal and left occipital lobes without significant mass effect on the adjacent brain parenchyma. No subarachnoid hemorrhage is identified on this examination.2. The vasculature in the brain and neck are patent without evidence of flow limiting stenosis, aneurysm or vascular malformation. Please note, however, that the V2 and V3 segments of the vertebral arteries are not well visualized due to field of view limitations.
