 MRI brain:The study is motion degraded. The morphology of the brain parenchyma is within normal limits. There are a few scattered foci of white matter T2 hyperintensity, which is nonspecific but compatible with mild chronic small vessel ischemic changes. There is no restricted diffusion abnormality or abnormal signal on susceptibility weighted imaging. The ventricles and sulci are within normal limits. There is no midline shift or mass effect. No extra-axial fluid collection is identified. The orbits appear normal without evidence of mass. The midline structures and craniocervical junction are within normal limits. MRA brain:Image quality is suboptimal. The anterior and posterior intracranial circulation is patent. There is no evidence of aneurysm, vascular malformation, or flow limiting stenosis. There is fetal origin of the left PCA.
1.Mild chronic small vessel ischemic changes, but otherwise normal MRI brain for patient age. If there is high suspicion for orbital pathology, consider dedicated MR imaging of the orbits. 2.Normal MRA brain without evidence of PCA aneurysm.
