Female, 8 years old, with tuberous sclerosis and epilepsy, evaluate SEGA and cortical tubers for change. Numerous scattered areas of cortical thickening and subcortical T2 hyperintensity are redemonstrated in the cerebral hemispheres without significant interval change. Likewise, numerous subependymal nodules are demonstrated showing variable enhancement and susceptibility effect, also without change. The largest lesions, and those with the most conspicuous enhancement, are found at the bilateral foramina of Monro and measure up to 16 mm in length.No new lesions are appreciated. No significant generalized mass effect is detected. There are no findings to suggest acute intracranial hemorrhage. The ventricular system is stable in size and morphology.
Multiple stigmata of tuberous sclerosis are redemonstrated without significant interval change. This includes prominent enhancing subependymal lesions at the foramina of Monro which may represent SEGAs.
