55 years Female (DOB:6/27/1961)Reason: intracranial stenosis History: unexplained syncopal episodesPROVIDER/ATTENDING NAME: RIMAS V LUKAS RIMAS V LUKAS MRI of the brainNo diffusion weighted abnormalities are appreciated.The CSF spaces are appropriate for the patient's stated age with no midline shift. Punctate focus of signal hypointensity is present along the left foramen of Luschka .It can be identified on a prior CT of the head from 3/30/2016 is a calcification. It could be part of the choroid.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 right transverse sinus is small. The right jugular vein is smaller than the left jugular vein.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 duplication of the right middle cerebral artery presentThere is no evidence for intracranial aneurysm or cerebrovascular occlusion.The anterior communicating artery is identified and is small. The posterior communicating arteries are small. The left vertebral artery is larger than the right vertebral artery.
1.No evidence for cerebrovascular occlusive disease.2.No evidence for intracranial aneurysm.3.There is no evidence for acute ischemic cerebral infarction.4.There is no evidence for an intracranial mass lesion.
