History of multiple sclerosis and lupus presenting with worsening left-sided weakness and gait instability. Assess for new lesions. Redemonstration of multiple foci of periventricular and subcortical white matter with increased T2 signal compatible with the history of multiple sclerosis. There are no new lesions identified. No lesional enhancement is noted on the postcontrast images. T1 hypointensity associated with multiple lesions again seen. Brain parenchymal volume is grossly preserved. No acute ischemia. There is no evidence of intracranial hemorrhage. No intracranial mass or mass effect. The ventricles and basal cisterns are normal in size and configuration. The expected intracranial vascular flow voids are present. Calvarium and extracranial soft tissues are within normal limits.
1. Multiple supratentorial and infratentorial white matter lesions compatible with the history of multiple sclerosis. No new lesions are identified. No lesions with enhancement to suggest active demyelination. 2. No evidence of acute ischemia, hemorrhage, or intracranial mass effect.
