Info
  • extensive T2/FLAIR cortical and subcortical white matter regions of hyperintensity due to cortical and subcortical tubers

  • subependymal nodules (hamartomas), which demonstrate a low T2/FLAIR signal in keeping with calcification

  • multiple hyperintense bands radiating from the periventricular region to the cortical surface (radial band sign)

Case Discussion

This case demonstrates typical MRI findings of tuberous sclerosis of the brain with cortical and subcortical tubers, calcified sub-ependymal nodules, and hyperintense radial bands.
