Female, 38 years old, with multiple sclerosis and paresthesias, assess for progression. Innumerable T2 hyperintense lesions are again seen in the periventricular white matter, brainstem and posterior fossa consistent with multiple sclerosis. On comparison with prior examinations, the majority of these lesions are stable or improved. For example, a prominent lesion in the medulla, and another at the level of the right facial colliculus, have distinctly decreased in size. Only one lesion in the right periventricular white matter (image 22 series 5) shows some equivocal evidence of increasing size.No evidence of mass effect is detected. No entirely new lesions are seen. The corpus callosum is thinned and there is likely some degree of mild central volume loss. The ventricular system is otherwise within normal limits. No abnormal collection or evidence of intracranial hemorrhage is seen.
Innumerable white matter lesions are redemonstrated compatible with multiple sclerosis. Overall, these lesions are stable or reduced in size. Only one lesion in the right periventricular white matter shows some evidence of increased size, but even this is equivocal.
