title: Delayed appearance of posttraumatic cerebrospinal fluid fistula.

Attention was drawn to the CSF fistula only after recurrent meningitis and detailed imaging studies. Using a right frontal craniotomy approach, successful repair of the CSF fistula was performed and patient was discharged symptom-free.
