case_images: Sagittal (a) and axial (b-d) MRI scans showing tetrahydrocephalus and the third ventricular floor downward bulging, which can be suggestive of noncommunicating hydrocephalus.

case_images: As we noticed that the MRI showed third ventricular dilation with downward bulging of its floor [Figure 1], a typical characteristic of noncommunicating hydrocephalus, we decided to perform a CT ventriculography that showed a complete FVOO [Figure 2].
case_images: Sagittal (a) and coronal (b) CT ventriculography showing the flow obstruction of contrast circulation ate the level of the fourth ventricle apertures.
