Cerebral Herniation

Last Updated: October 1, 2018

Figure 1: The suprasellar cistern is effaced and the right temporal horn is medialized on this head CT indicating uncal herniation. The findings were due to mass effect from a large hematoma and hydrocephalus (not pictured).

Figure 2: The FLAIR (top row left) and DWI (top row right) hyperintensity in the midbrain represent a nonspecific insult, but when combined with known recently decompressed trantentorial herniation and low signal intensity susceptibility artifact on GRE (bottom row), this abnormality likely represents a Duret hemorrhage.
