Abstract
-
The Meckel's cave is a dural recess containing trigeminal nerve and ganglion, extending from the posterior fossa into the middle cranial fossa. Using MRI, internal architecture in the Meckel's cave can be discernible, even a small nodule within it can be detected. There are a wide spectrum of disease process occurring in and or in the vicinity of the Meckel's cave. Disease can be classified into pathology of the trigeminal nerve proper, within the trigeminal cistern and outside the trigeminmal cistern. These classification depending on the location will aid in interpretation of pathology of Meckel's cave. We will demonstrate the MR anatomy and various pathologies of the Meckel's cave.
