Tuberous sclerosis. There is no appreciable interval change in the numerous predominantly subcortical areas of T2 hyperintensity and multiple subependymal nodules, the largest of which are located adjacent to the bilateral foramina of Monro. The ventricles are unchanged in size and configuration, without evidence of obstructive hydrocephalus. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues appear unchanged.
