title: Spontaneous cerebral ventriculostium: two cases.
abstract: Two cases of `spontaneous cerebral ventriculostium' are reported. In one case the diagnosis was made during life, and the hydrocephalus was not relieved by the ostium. The unique feature of the other has been the presence of a large defect in the skull bones, posteriorly, which has been a `nature's help' towards maintaining the hydrocephalus stationary, after an initial period of progression.
