Tuberous Sclerosis Complex (TSC) is a genetic hamartoma syndrome frequently
associated with severe intractable epilepsy. In some TSC patients epilepsy
surgery is a promising treatment option provided that the epileptogenic zone can
be precisely delineated. TSC brain lesions (cortical tubers) contain dysmorphic
neurons, brightly eosinophilic giant cells and white matter alterations in
various proportions. However, a histological classification system has not been
established for tubers. Therefore, the aim of this study was to define distinct
histological patterns within tubers based on semi-automated histological
quantification and to find clinically significant correlations. In total, we
studied 28 cortical tubers and seven samples of perituberal cortex from 28 TSC
patients who had undergone epilepsy surgery. We assessed mammalian target of
rapamycin complex 1 (mTORC1) activation, the numbers of giant cells, dysmorphic
neurons, neurons, and oligodendrocytes, and calcification, gliosis, angiogenesis,
inflammation, and myelin content. Three distinct histological profiles emerged
based on the proportion of calcifications, dysmorphic neurons and giant cells
designated types A, B, and C. In the latter two types we were able to
subsequently associate them with specific features on presurgical MRI. Therefore,
these histopathological patterns provide consistent criteria for improved
definition of the clinico-pathological features of cortical tubers identified by
MRI and provide a basis for further exploration of the functional and molecular
features of cortical tubers in TSC.
