title: Bilateral optic canal meningiomas: a case report.
abstract: In the case presented, bilateral optic canal meningiomas produced binocular visual loss. Correct diagnosis was delayed because of inadequate and misinterpreted radiological studies. Careful radiological and surgical examination of the planum sphenoidale later suggested this as the source of both canalicular masses. The pertinent aspects of this case are reviewed in relation to information from similar cases reported previously. In the future, increased clinical suspicion and more accurate neuroradiological studies should improve the detection and afford earlier surgical treatment of meningiomas of the optic canal.
