Cortical/subcortical tubers: displaying high T2 and FLAIR and low T1 signals.
Subependymal hamartomas with variable signal intensities in T1,T2 and FLAIR.
White matter abnormalities in the form of:
- Two small cystic lesions seen at the right frontal and left posterior parietal regions ranging up 1 cm.
- Radial bands (thought to be relatively specific for TS): very characteristic linear bands most appreciated on the T2 WIs seen radiating from the periventricular white matter (Just posterior to the bodies of both lateral ventricles) to the subcortical region.
