A 46-year-old female with left V1/V2 trigeminal neuralgia had imaging showing a non-enhancing lytic lesion of the left petrous apex without typical features of a pseudo-meningocele. An endoscopic endonasal transclival approach was performed, revealing clear fluid within the lesion consistent with a CSF-filled pseudo-meningocele. The defect was repaired using fat and mucosal grafts. Postoperative recovery was uneventful, with no CSF leak, and the patient had full resolution of her neuralgia.
