The trigeminal cave (also known as Meckel’s Cave or cavum trigeminale) is an arachnoidal pouch containing cerebrospinal fluid. It 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:1. The cerebellar tentorium superolaterally2. The lateral wall of the cavernous sinus superomedially3. The clivus medially4.
