Male, 38 years old, with paresthesias and history of multiple sclerosis. Evaluate for progression. Numerous juxtacortical, periventricular, corpus callosum and brainstem T2 hyperintense lesions are redemonstrated. These appear similar in size, number and distribution when compared to the prior examination. Several of these lesions, two along the left lateral ventricle and one along the right lateral ventricle, demonstrate marked T1 hypointensity. Other lesions demonstrate mildly to moderately reduced T1 signal. The T1 characteristics of these lesions do not appear to have significantly changed.Brain parenchymal morphology is otherwise unremarkable. No mass effect or edema is suspected. Brain volume appears to be preserved. The ventricles are normal in size and morphology. No abnormal extra-axial collections are detected.
No significant interval change in the size, number or imaging characteristics of numerous lesions compatible with multiple sclerosis.
