title: Recurrent meningitis associated with a petrous apex cephalocele.
abstract: We present the case of a 6-year-old girl with recurrent bacterial meningitis and cerebrospinal fluid (CSF) rhinorrhea associated with a petrous apex cephalocele (PAC). We diagnosed her by means of three-dimensional computed tomography (CT) and heavily T2-weighted magnetic resonance imaging (MRI). Petrous apex cephaloceles are usually an asymptomatic incidental finding in adults; however, they should be considered as a possible cause of CSF rhinorrhea, otorrhea, and recurrent meningitis in children.
