Tuberous sclerosis is a neurocutaneous autosomal dominant syndrome, in which angiofibromas appear in childhood in the nasolabial folds and on the central face [2]. The finding of a sub-ependymal giant cell astrocytoma is sometimes seen in patients with tuberous sclerosis, and the finding of a subependymal hyperdense enhancing lesion is consistent with this diagnosis.  |  Brain. It usually presents in early childhood, and other skin features include facial angiofibromas or periungual fibromas. Inheritance is autosomal dominant with variable expressiveness and incomplete penetrance. Tuberous Sclerosis Complex (TSC) is a multi-system genetic disorder with a birth incidence of approximately 1 in every 6000.

[24] However, these develop at a much later age than the angiofibromas of TSC. The presence of multiple bilateral subependymal nodular nonenhancing hyperdense calcified lesions is relatively characteristic of tuberous sclerosis when combined with the appropriate clinical findings.
