MRI brain revealed [Figures 1 and 2] the classic features of IH including subdural hematoma collection, descent of cerebellar tonsils, effacement of the prepontine cistern and interpeduncular cistern, inferior displacement of the optic chiasm, reduced mammillary body and pontine distance due to the descent of the mammillary body, crowding of posterior fossa due to brainstem descent, descent of cerebellar tonsils, sagging of tuber cinereum, inferior displacement of splenium, and descent of the fastigium of the fourth ventricle.
