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

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].
Sagittal (a) and coronal (b) CT ventriculography showing the flow obstruction of contrast circulation ate the level of the fourth ventricle apertures.
