MRI shows the subependymal nodules to be isointense on T1 and T2 with blooming on GRE - in keeping with the known calcification. The largest, right frontal nodule is enhancing. However, we've compared this MR to previous studies, and it has been stable in size and degree of enhancement for several years.
