Third ventricular cysts and membranes unsuspected on conventional CT and MRI.
Three cases are presented of symptomatic cysts or membranes within the third ventricle interfering with CSF flow and presenting as non-communicating triventricular hydrocephalus. None was visible on conventional CT or MRI, two being discovered at neuroendoscopy and one only with a specific MRI sequence designed to show CSF partitioning.
