title: Transcranial approach for spontaneous CSF rhinorrhea due to Sternberg's canal intrasphenoidal meningoencephalocele: case report and review of the literature.
abstract: One type of congenital intrasphenoidal meningoencephalocele is remnant of     lateral craniopharyngeal (Sternberg's) canal. We present a case of a 23-year     girl with 10-month history of right side CSF rhinorrhea. CT scan, MRI revealed     congenital meningoencephalocele and CSF leak from middle fossa to right side of     sphenoid sinus, and there were bony defects at the floor of the anterior aspect     of the right middle fossa. Transcranial repair was performed with right side     pterional craniotomy. Careful preoperative evaluation and localization of the     sphenoid defect are essential for selection of the best possible surgical     approach and skull base reconstruction for repair of sphenoid sinus CSF leaks     and meningoencephaloceles. In this case, an endoscopic technique was not     successful so, transcranial repair was performed with right side pterional     craniotomy.
