 There is persistent severe hydrocephalus with essentially unchanged thin ribbon of gray and white matter surrounding the ventricular cavities. There is associated enlargement and deformity of the calvarium. There is somewhat increased bowing of the thinned brainstem towards the left due to the right lateral ventricle, resulting in new compression of the 4th ventricle. There is a left parietal approach ventriculostomy catheter. The septum pellucidum is absent. There is no evidence of intracranial hemorrhage. The major cerebral flow voids are intact.
