Upwards transtentorial cerebellar herniation – http://id.who.int/icd/entity/496106804

Upward transtentorial refers to mass effect in the posterior fossa displacing the midbrain upward. This may produce diffuse symptoms of obstructive hydrocephalus if the cerebral aqueduct or fourth ventricle are occluded, or homonymous hemianopsia if the posterior cerebral artery (PCA) impacts on the tentorial edge.
