Neuroimaging results were available in 115 infants, of whom 94% had tubers or cortical dysplasias, 90% had SENs, and 89% had both; 6% had subependymal giant cell astrocytomas.
68-73) In one such study, a mouse model in which transgenic Gfap promoter-driven expression of PDGFB was superimposed upon a Tp53-null background not only generated GBM-like lesions in mice, but also intriguingly demonstrated hyperplastic astroglial lesions in both subependymal and subpial locations, possibly representing precursor lesions.

Our patient was a 32-year-old male, non-hypertensive, non-diabetic, who fulfilled five major criteria (facial angiofibromas, periungual fibromas, ash leaf spots, cortical dysplasia, subependymal nodules (SEN), renal angiomyolipomas) of tuberous sclerosis complex (TSC) as per diagnostic criteria of the 2012 International Tuberous Sclerosis Complex Consensus Conference (Box 1).
Circumscribed gliomas include juvenile fibrillary astrocytomas, pleomorphic xanthoastrocytomas and subependymal giant cell astrocytomas.

Subependymal nodular heterotopias (SNHs) are one of the most frequent malformations of cortical development.
SENs = subependymal nodules; MRI = magnetic resonance imaging; CT = computed tomography; SEGA = subependymal giant cell astrocytoma.
These are due chiefly to intractable epilepsy, status epilepticus, and subependymal giant cell astrocytoma (SEGA) with associated hydrocephalus.
In the examinations made for multi-organ involvement, minimal foor rhythm irregularity in EEG and calcified subependymal hamartoma, calcified tuber and astrocytomal appearance were observed.
The scan revealed the presence of bilateral, diffuse subependymal nodules along the walls of the lateral ventricles, which had the same signal intensity as grey matter on T1W, T2W, FLAIR and IR sequences, with no blooming artefact on T2W FFE and no enhancement post contrast (Figure 1).
In the EU, Votubia tablets are also approved for the treatment of adult patients with renal angiomyolipoma associated with TSC who are at risk of complications but who do not require surgery, as well as treatment for patients with subependymal giant cell astrocytoma (SEGA) associated with TSC who require therapeutic intervention but are not amenable to surgery.
