title: Aneurysmal cyst of the petrosal bone.
abstract: An aneurysmal cyst of the petrosal bone presenting as hearing loss and recurrent bacterial meningitis is reported. None of the clinical or radiographic signs described previously were present. Because other diagnostic methods are not reliable, it is recommended that coronal thin section computed tomography be performed in every case of suspected malformation of the skull base and in the diagnosis of recurrent bacterial meningitis.
