DOI : 10.5137/1019-5149.JTN.7098-12.0 Delayed posttraumatic cerebrospinal fluid rhinorrhea (CSFr) without meningitis is considered to be relatively rare. However, even years after trauma, recurrence or delayed onset of CSFr and meningitis due to CSFr are possible. In this article, a case of delayed CSFr from the sphenoid sinus without meningitis three years after the transfacial gunshot wound is reported. Plain high-resolution computed tomography sections through the sphenoid sinus showed a bone defect at the roof with CSF-density fluid extending into the sphenoid sinus. Arachnoid membrane herniation into the sphenoid sinus was found and site of CSF fistula confirmed during the surgery. Skull base defect was reconstructed through an endoscopic approach without any complications and the patient was followed up for 12 months without recurrence. The cause, timing, clinical course and location of CSFr make this an apparently unique case. Patients with a skull base defect without CSFr should be closely followed up and may need further evaluation or management due to the possibility of CSFr development. The positive diagnosis of a CSFr raises the matter of choosing the adequate surgical approach for its repair. Endoscopic closure of CSFr is both safe and effective.
