"Cortical tubers, or hamartomas, are the most characteristic lesions of tuberous sclerosis. The appearance of cortical tubers on MRIs varies with patient age. In neonates and young children, the cortical tubers and subependymal nodules are hyperintense on T1-weighted images and hypointense on T2-weighted images. In older children and adults, the cortical and subependymal lesions are isointense or hypointense on T1-weighted images. They are hyperintense relative to gray matter, as well as white matter, on T2-weighted images, depending on the presence of calcification."
