Meckel's cave is a dural recess in the posteromedial portion of the middle cranial fossa that acts as a conduit for the trigeminal nerve between the prepontine cistern and the cavernous sinus, and houses the Gasserian ganglion and proximal rootlets of the trigeminal nerve.

The anatomy of the trigeminal cavum also known as Meckel's cave is still poorly understood despite the number of various descriptions available in the literature. The new concept of parasellar compartment means that Meckel's cave and the cavernous sinus constitute a unique entity. We sought to understand anatomic organization of the trigeminal cavum through dissection of 5 previously frozen.

Meckel cave tumors account for only 0.5% of all intracranial tumors. The most common histologies are: trigeminal schwannoma : most common, ~33% of cases meningioma pituitary macroadenoma base of skull tumors metastases : including retrograde spread of head and neck tumors neurolymphomatosis epidermoid cyst lipoma Non-neoplastic

Accessing Meckel's cave (MC) is surgically challenging. Open approaches are complex and often correlated with high morbidity. Endoscopic approaches emerged in the last decade as feasible alternatives to open approaches, especially for sampling indeterminate lesions.

Meckel's cave is a natural mouth-shaped aperture in the medial portion of the middle cranial fossa that acts as a key conduit for the largest cranial nerve, the trigeminal nerve (CN V). It connects the cavernous sinus to the prepontine cistern of the posterior fossa.

Introduction. Cavum-trigeminale-cephaloceles (CTCs) are rare lesions of Meckel's cave and the petrous apex with few reports on their typical neuroradiological features [1], [2], [3].. Despite their distinctive imaging findings, CTCs are frequently mistaken for other petrous apex lesions such as cholesterol granulomas, mucoceles, cholesteatomas and effusion or inflammation of the petrosus apex.

Introduction. Named after Johann Friedrich Meckel, a German anatomist, the cavum meckeli, also known as Meckel's cave, trigeminal cave or cisterna trigeminalis, is a region with a complex neurovascular array and, therefore, anatomically speaking, presenting a surgical challenge.. Meckel's cave is located at the petrous apex between two dural layers originating from the floor of the middle.

The trigeminal cave (also known as Meckel's cave or cavum trigeminale) is a pouch of dura mater containing cerebrospinal fluid . Structure The trigeminal cave is formed by the two layers of dura mater (endosteal and meningeal) which are part of an evagination of the cerebellar tentorium near the apex of the petrous part of the temporal bone.
