Cortical tubers are malformative lesions in the CNS observed in tuberous sclerosis complex (abbreviated TSC), an autosomal dominant syndrome.
General
- Cortical tubers are malformative, epilepsy-associated.[1]
- Seen in 80-90% of the TSC cases.
- Gyrus is usu. thickened, raised, and occasionally dimpled.
- Giant cells, dysmorphic neurons, disrupted cortical lamination, gliosis, calcifications.
- Ballon cells are Vim+ve, MAP2+ve, Nestin+ve, GFAP+/-ve, NeuN+/-ve.
- TSC2 has larger and more numerous tubers.[2]
DDx
- Focal cortical dysplasia ILAE type IIB (Tubers are usu. multifocal).
