56 years Male (DOB:6/4/1960)Reason: L MCA stroke - MRI brain stroke protocol History: as abovePROVIDER/ATTENDING NAME: KEEGAN CHECKETT KEEGAN CHECKETT MRI of the brainThere is diffusion restriction present along the left lentiform nuclei involving predominantly the putamen and extending to the adjacent left centrum semiovale.The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Exam is mildly degraded due to patient motion especially on the FLAIR MRI . 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, right middle and posterior cerebral arteries.There is occlusion of the left middle cerebral artery at the M1 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.
1.Findings are compatible with acute ischemic infarction involving left putamen and centrum semiovale.2.Occlusion of the left middle cerebral artery at the proximal M1 segment.3.Examination is somewhat degraded by patient motion which may obscure more subtle abnormalities.4.Findings are discussed with Dr. Kramer at the time of exam.
