The trigeminal cave (also known as Meckel's cave or cavum trigeminale) is an arachnoidal pouch containing cerebrospinal fluid.
Structure
The trigeminal cave is formed by two layers of dura mater which are part of an evagination of the tentorium cerebelli near the apex of the petrous part of the temporal bone. It envelops the trigeminal ganglion. It is bounded by the dura overlying four structures:
- The cerebellar tentorium superolaterally
- The lateral wall of the cavernous sinus superomedially
- The clivus medially
- The posterior petrous face inferolaterally
History
Etymology
It is named for Johann Friedrich Meckel, the Elder.[1][2]
