76 years Female (DOB:7/11/1939)Reason: eval for vascular malformation History: eval for vascular abnormalityPROVIDER/ATTENDING NAME: JOSHUA D MOSS JOSHUA D MOSS MRI of the brainThe focus of questionable enhancement along the ependymal and intraventricular focus in the trigone of the left lateral ventricle contains the left lateral atrial vein extending into the vein of Galen as well as a portion of the left choroid plexus.A small amount of blood layers in the occipital horn of the left lateral ventricle.No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.MRA brain:Antegrade flow is present in the distal internal carotid arteries, the distal vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries.There is fenestration of the right A2 segment.There is no evidence for intracranial aneurysm or cerebrovascular occlusion.The anterior communicating artery is identified. The posterior communicating arteries are not readily identified. The vertebral arteries are similar in size. There is extracranial origin the left posterior inferior cerebellar artery.
1.The parenchymal lesion at the anterior aspect of the trigone of the left lateral ventricle appears to represent a confluence of the draining vein and choroid plexus. 2.No evidence for cerebrovascular occlusive disease.3.No evidence for intracranial aneurysm or arteriovenous malformation.4.A small amount of blood layers in the occipital horn of the left lateral ventricle. This was also identified in the recent CT exam.
