 MRI BRAIN:Mildly prominent ventricles and sulci indicating volume loss. The basal cisterns remain patent. There is no midline shift or mass effect. Moderate scattered periventricular and subcortical T2 hyperintensities are nonspecific but likely related to chronic small vessel ischemic disease. There is a small amount of cystic change in the left periventricular white matter lesions. T2 hyperintensities within the bilateral putamen likely reflect chronic lacunar infarcts. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. Mild mucosal thickening of the bilateral maxillary sinuses, right greater than left.MRA BRAIN:No significant stenosis or aneurysm in the anterior or posterior circulation. Fetal origin of the left posterior communicating artery. Dominant left vertebral artery.
1.No acute abnormality.2.Mild to moderate chronic small vessel ischemic disease.3.No significant stenosis or aneurysm on MRA.
