Please evaluate for SEGA, hydrocephalus, or other tumors: TS with intractable epilepsy. There are numerous T2 hyperintense cortical and subcortical lesions in the bilateral cerebral hemispheres, some of which extend towards the lateral ventricles in a linear configuration. There is no evidence of acute intracranial hemorrhage or acute infarct. There are multiple nodules involving the bilateral lateral ventricles, the largest of which measure up to 7 mm in the bilateral foramina of Monro regions. The ventricles are otherwise not particularly enlarged. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Stigmata of tuberous sclerosis complex, including numerous "tubers" and subependymal nodules, but no evidence of SEGA and hydrocephalus.
