 There are approximately 10 punctate foci of T2 and FLAIR hyperintensity within the supratentorial white matter, primarily within the bilateral frontal lobes. These are nonspecific in appearance and distribution and may be related to prior inflammation, ischemia or perhaps demyelination. No infratentorial lesions. There is no abnormal intracranial enhancement or diffusion abnormality. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles, sulci and basal cisterns are normal in size and configuration. There is no midline shift or herniation. No extra-axial fluid collection is identified. Normal flow-voids are demonstrated in the major intracranial vascular structures. Mild cerebellar tonsillar ectopia is noted, with descent of the tonsils approximately 5 mm below the level of the foramen magnum. MRI ORBITS
1. Scattered punctate foci of T2/FLAIR hyperintensity within the supratentorial white matter are nonspecific in appearance and distribution and may be related to prior inflammation, ischemia or perhaps demyelination (although not typical for demyelination).2. There is significant motion degradation of the orbital MRI sequences which limits evaluation for optic neuritis. Within this limitation however no obvious signal abnormality within the optic nerves or orbital mass is evident.3. Low-lying cerebellar tonsils incidentally noted.
