Unspecified cause of encephalitis, myelitis, and encephalomyelitis Lack of coordination There is generalized cerebellar atrophy present associated with some mild FLAIR signal hyperintensity. The inferior aspect of the vermis is atrophic.. A comparison CT study from 2008 also demonstrates cerebellar atrophy. The fourth ventricle appears relatively large. There is no associated contrast enhancement.Postcontrast imaging is degraded due to patient motion. There is no associated leptomeningeal enhancement.There is metallic artifact adjacent to the left parietal bone.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate minor opacities. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is cerebellar atrophy present associated with signal hyperintensity along the cerebellum. The possibility of recurrence of cerebellitis is raised. Additionally, the general appearance of the cerebellum is suggestive of a Dandy-Walker variant.2.Metal artifact along the left parietal skull area is of unknown cause. It partly obscures visualization. Please correlate with clinical exam and clinical history.
