Tuberous sclerosis is a disease characterized by the presence of hamar
tomatous nodules in various organs, including the brain. Thirteen CT s
cans and four MR investigations were performed in 13 patients. CT is s
uperior to MR in demonstrating the presence of subependymal nodules, t
hereby confirming or establishing the diagnosis of tuberous sclerosis.
MR is superior to CT in demonstrating the peripheral lesions, which a
re characterized by a long T2-relaxation time. Differentiation between
cortical tubers and subcortical lesions is not yet accurate.
