Objective: To report a rare case of delayed spontaneous cerebrospinal fluid (CSF) leak through clival region in the sphenoid sinus.

Case report: A 35-year-old female presented to our outdoor clinic with watery right nasal discharge for past 2 months, which increased on bending forward. Her medical history, general physical and neurological examinations were unremarkable. High-resolution computed tomographic scan and magnetic resonance cisternography were performed and suggestive of defect in right cribriform plate and right sphenoid sinus. Endoscopic repair was done but same symptoms occurred after 1 month. Repeat magnetic resonance imaging showed fistula in the lateral wall of right sphenoid sinus. Revision endoscopic transnasal CSF rhinorrhea repair was done. Lumbar subarachnoid drain was left in place for 5 days. No recurrence was noted at 12-week follow-up.

Conclusion: Endoscopic transnasal approach is the best modality of treatment for midline skull base defects. Delayed leaks can present from previously weak areas and all the doubtful areas must be examined during surgery.

Keywords: Clival recess, Endoscopic repair, Spontaneous cerebrospinal fluid leak.
