Abstract

Objective: To present a case of successful repair of a spontaneous cerebrospinal fluid leak in a previously unreported anatomic site. Methods: Retrospective chart review. Results: A 48-year-old woman developed a spontaneous cerebrospinal fluid leak from the optic nerve sheath and underwent a multilayer endoscopic closure with no damage to the optic nerve. Conclusion: Endoscopic surgeons can successfully repair cerebrospinal fluid leaks from the optic nerve sheath without causing loss of vision.
