Cranial computertomography in children with tuberous sclerosis.

20 children with tuberous sclerosis were examined by computertomography (CCT). The test is useful to detect cerebral involvement with great certainty. The method is especially helpful in the early diagnosis of the disease. This offers the possibility of giving an early genetic advice. Characteristic CCT scan abnormalities in tuberous sclerosis are multiple densities in the walls and the roof of lateral ventricles. This specific finding can already be seen prior to the occurrence of calcifications in standard roentgenograms.
