During treatment there was a rapid reduction of BBB abnormalities in 96% of enhancing lesions. In spite of sustained clinical improvement, many lesions re-enhanced within a few days of stopping IVMP, and new lesions frequently appeared within one month. It is possible that the rapid, albeit transient, reversal of BBB abnormalities contributes to the accelerated recovery from relapses associated with IVMP treatment.
