Meningioma in the pineal region: preoperative diagnosis with CT, MRI, and angiography.
We report a case of pineal region meningioma. The nature of the tumor was correctly diagnosed mainly from the angiographic findings, which enabled us to avoid unnecessary irradiation therapy. Retrospective readings of the CT and MR findings also indicated that the tumor arose apart from the pineal body and appeared to be attached to the dura at the falcotentorial junction. The differential diagnosis of pineal region tumors is discussed.
