Because surgical risk depends largely on tumor size and vascularity (,22,,24,,25), CT and MR imaging are useful for noninvasive evaluation. Figure 2b.

Tuberous sclerosis complex (TSC) is an autosomal dominant inherited neurocutaneous syndrome characterized by various hamartomatous lesions in various organs . Subependymal nodules tend to have lower signal intensity on T2-weighted image than do cortical tubers, probably because subependymal nodules have high water content (,14). Most cases represent new (sporadic or de novo) gene mutations, with no family history of the disease. 10, 6 May 2019 | RadioGraphics, Vol. Figure 14b.

However, recent meta-analysis has shown that the overall incidence of renal cell carcinomas in patients with TS is identical to that in the general population (,52). The diagnosis in affected patients is usually made in early adulthood, and the symptoms are commonly dyspnea on exertion or recurrent pneumothorax. Tuberous sclerosis complex (TSC) is a rare autosomal dominant neurocutaneous syndrome characterised by benign congenital tumours affecting multiple organs, most frequently the brain, eyes, kidneys, heart and skin. Subependymal tubers in a 26-year-old woman.
