 　We report a case of meningocele of the temporal bone. A 22-year-old female consulted our hospital complaining of high grade fever and vomitting. Meningitis was detected and treated with antibiotics. About one month after the initial hospitalization, meningitis recurred. CT examination demonstrated bone defect at the skull base of mastoid cavity. We diagnosed this patient as having cholesteatoma or meningocele.
　Surgery was performed by the trans-mastoid approach. After mastoidectomy, a round mass was found and the mass decreased after leakage of liquor. Meningocele of the temporal bone was confirmed. Reduction of meningocele was performed using bone fragment and temporal muscle. Postoperatively, there has not been any recurrence of meningitis to date.



Key words : meningocele, temporal bone, meningitis
