MRI features to aid the identification of lateral temporal bone cephaloceles.

Objectives: To evaluate ancillary MRI features which may aid the identification of lateral temporal bone cephaloceles (LTBCs).

Methods: A retrospective cohort study analysed patients with MRI evidence of surgically confirmed spontaneous LTBCs as defined by intracranial contents traversing the tegmen tympani or mastoideum. Cases were identified from radiology and surgical databases.
