Magnetic resonance imaging confirmed the presence of a mucocele. A left endoscopic sphenoidotomy was performed to drain the mucocele. Despite an anatomical puncture through a stenosed sphenoid ostium, alarmingly, the opening leaked cerebrospinal fluid. A dehiscent lateral wall was identified with a dural opening communicating with the sphenoid sinus. This was immediately repaired with a free nasal septal mucosal graft. Six months post-operatively, the patient remained free from cerebrospinal fluid leakage.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215113002247_sec3\"><jats:title>Conclusion:<\/jats:title><jats:p>Pseudomeningoceles are extremely rare in the absence of trauma or iatrogenic injury.
