Cerebrospinal fluid leak with recurrent meningitis following tonsillectomy Case report

The authors report an unusual case of bilateral large petrous apex cephaloceles in a 14-year-old boy with a history of recurrent meningitis. Although these lesions are rare and Usually asymptomatic, surgical correction is recommended if they are associated with a persistent CSF leak. In this patient, the extensive bilateral cranial defects were not adequately treated by an intracranial approach alone. Repair of a defect in the posterior pharyngeal wall, the site of a prior tonsillectomy,, ultimately resulted in repair of the CSF fistula. (DOI: 10.3171/2009.10.PEDS09336)
