descending transtentorial herniation
the most common kind of transtentorial herniation, with downward displacement of the most medially-placed cerebral structures through the tentorial notch, compressing parts of the cerebrum and structures beneath the notch; it is caused by a supratentorial mass. Symptoms depend on which structures are compressed and may include ocular changes or hemiparesis. Called also caudal transtentorial h.
