History of tuberous sclerosis and intractable epilepsy with known SEGA. There is mild motion degradation. The large enhancing mass/SEGA at the left foramen of Monro is unchanged in size, measuring 16 x 14 x 17 mm (AP by TR by CC). The ventricles and sulci are stable. The known multiple small subependymal nodules appear stable. The lesion in the right lateral ventricular trigone again measures 6 mm. There are also multiple foci of increased T2 signal within the cortical and subcortical regions, which are unchanged from the prior study. There is no evidence of intracranial hemorrhage or acute infarct. There is no midline shift or herniation.
Stable appearance of stigmata of tuberous sclerosis, including presumed subependymal giant cell astrocytoma at the left foramen of Monro.
