A Case of Petrous Apex Meningocele: Unusual Presentation of Cerebrospinal Fluid Leak Following Adenoidectomy

Abstract

Cerebrospinal fluid (CSF) leak is possible and can be a cause of recurrent bacterial meningitis. Petrous apex meningocele (PAM) is mostly asymptomatic and is often found during incidental imaging tests. We experienced a case of CSF rhinorrhea with recurrent meningitis in bilateral PAM after adenoidectomy. This report highlights the diagnostic process of CSF leak, identification of leakage site, and surgical approach to petrous apex lesions.
