Tuberous sclerosis complex: intractable epilepsy and autism. There is no significant interval change in size of the lobulated enhancing mass with areas of susceptibility effect in the left lateral ventricle, which measures up to 32 mm, previously 32 mm. There is persistent mild vasogenic edema in the surrounding brain parenchyma. There is also an enhancing mass within the right lateral ventricle, which measures up to 8 mm, previously 8 mm. There is slightly decrease prominence of the lateral ventricles, which are mildly dilated, and slightly increased diffuse periventricular white matter T2 hyperintensity. There is no significant interval change in numerous foci of subcortical T2 hyperintensity, some of which demonstrate enhancement. There is no evidence of intracranial hemorrhage or acute infarct. There is a right cerebellar hemisphere developmental venous anomaly. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable. There is left tympanomastoid fluid has resolved.
1. No significant interval change in size of bilateral lateral ventricular subependymal giant astrocytomas, left larger than right.2. Other stigmata of tuberous sclerosis are also not significantly changed.3. Interval resolution of the left tympanomastoid fluid.
