Mucocele of the anterior clinoid process: A comprehensive literature review and report of two cases

Abstract

Anterior clinoid process (ACP) mucocele is a rare phenomenon, which is developed by mucous entrapment with in pneumotized ACP. Its clinical presentation is so varying according to its compression on surrounding neurovascular structures. Lack of characteristic imaging appearance and clinical presentation made its diagnosis complicated. Delay in its diagnosis may lead to irreversible devastating neurological (especially ophthalmologic) symptoms despite of efficient therapeutic strategy. In this regard, we do a literature review about ACP mucocele, then present our two patients with ACP mucocele with explanation of our therapeutic decisions according to their clinical course.
