New focal left upper extremity weakness and hyperesthesia; started cyclosporin yesterday for severe ulcerative colitis, also on high dose steroids, but no recorded hypertension episodes. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are apparent faint areas of heterogeneity in the cerebral white matter. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Apparent faint areas of heterogeneity in the cerebral white matter may be artifactual or less likely represents early toxic encephalopathy. Otherwise, no evidence of intracranial hemorrhage, or posterior reversible encephalopathy syndrome.
