Dizziness and giddiness [R42], Reason for Study: ^Reason: lesion on CT History: Lefts sided weakness Brain MRIMultifocal brain parenchymal lesions with high signal intensity on T2/FLAIR images were seen involving right superior frontal gyrus-pre central gyrus junction, left centrum semiovale, right parietal lobe posterior aspect of cingulate gyrus, right occipital gyrus, and left middle cerebellar peduncle. In particular, the right superior frontal gyrus - pre central gyrus junctional lesion shows peripheral enhancement indicating active inflammation. There is no evidence of acute ischemic or hemorrhagic lesion.Constellation of above findings indicate possible demyelinating disease such as multiple sclerosis. About 5mm cerebellar tonsilar ectopia through the foramen magnum.The ventricles, sulci and cisterns are symmetric and unremarkable. 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 pre and 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. Multifocal bihemispheric, supra and infra tentorial location, various sized brain parenchymal lesions showing high signal intensity on T2/FLAIR images with a Gad enhancing lesion indicating possible demyelinating disease such as multiple sclerosis.2. No evidence of acute ischemic or hemorrhagic lesion.3. Normal brain MRV.
