MR findings in extracerebral cavernous angiomas of the middle cranial fossa: report of two cases and review of the literature.

Extracerebral cavernous angioma is a rare entity; only 45 cases have been reported [1-32] . Thirty-seven of the angiomas, including the two cases reported here, were found in the parasellar region of the middle cranial fossa [1-26] . Differentiation from parasellar meningioma is known to be difficult, since the CT findings are similar. We report the MR findings in two cases of extracerebral cavernous angioma of the middle cranial fossa and review the literature.
