Unspecified convulsions [R56.9], Reason for Study: ^Reason: parieto-occipital hypodensity on CT head 12/28/16. Follow up study. History: abnormal CTH on 12/28/2016. Brain MRINo evidence of acute ischemic or hemorrhagic lesion on the scan.Bihemispheric patchy FLAIR/T2 high signal intensities on bilateral periventricular white matter indicate nonspecific small vessel ischemic disease.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.Brain MRV3D MRV brain post-gadolinium with maximum intensity projections of the superficial/deep intracranial venous drainage demonstrate normal flow enhancement in the superior sagittal sinus, transverse sinuses, sigmoid sinuses, internal cerebral veins, vein of Galen and straight sinus.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Non specific small vessel ischemic disease.3. Normal brain MRV.
