In some cases, cerebral cortical heterotopias are visualized as hypodense nonenhancing subependymal lesions. Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin.A combination of symptoms may include seizures, intellectual disability, developmental delay, behavioral problems, skin abnormalities, lung disease, and kidney disease.  |  Tuberous sclerosis is a multi-systemic disease with the defeat of ectoderm derivatives (skin, nervous system, retina) and mesoderm (kidney, heart, lungs). Angiomyolipoma should be considered within the differential for subcutaneous nodules and work-up for tuberous sclerosis should not be pursued when presenting in the skin. When there are multiple rabdomyomas the risk of tuberous sclerosis is >90%. Spring P, Fellmann F, Giraud S, et al. 1986 Nov;37(6):543-5. doi: 10.1016/s0009-9260(86)80009-5.
