Your report talks about brighter-than-normal signal on T2-weighted and FLAIR sequences (he said "inversion recovery" but I suspect he meant FLAIR). This is the "altered signal intensity" - these findings are pre-contrast. "Enhancement" relates entirely to the appearance of tissue
after gadolinium has been administered. So, "altered signal intensity" and "enhancement" are not the same thing.
