A unique case report of bilateral spontaneous cerebrospinal fluid leak from bilateral sphenoid sinus skull base defects

Abstract

To our knowledge, this case is one of the few documented examples of bilateral spontaneous CSF leaks from skull base dehiscence in the sphenoid sinus. Endoscopic sinus surgery provides a minimally invasive, effective repair. Anatomical variations, such as extensive sphenoid sinus pneumatisation and congenital defects, combined with factors such as high body mass index, may predispose patients to spontaneous CSF leaks.
