Male, 41 years old, with multiple sclerosis, CHORDS study. Multiple scattered T2 hyperintense lesions are again seen in the cerebral hemispheres and to a lesser extent the thalami, the capsular white matter, the brainstem, and cerebellum. A lesion in the cervical spinal cord at the C2 level is only visualized on the sagittal images. Accounting for differences in technique, the size and morphology of these lesions have not significantly changed. No new lesions are identified. The lesions demonstrate moderate to marked T1 hypointensity. On postcontrast images, there is faint wispy apparent enhancement along the roofs of the lateral ventricles which could reflect true enhancement, vascular structures or artifact. No evidence of parenchymal edema is seen. Ventricular size and morphology are within normal limits. Overall brain parenchymal volume is preserved.
Scattered parenchymal lesions are identified compatible with the history of multiple sclerosis. There has been no significant interval change in the size or number of these lesions.
