Objectives/Hypothesis: Meningioma is a neoplasm arising from cells related to the arachnoid villi. The aim of the present study was to explore the clinical and radiological characteristics of temporal bone meningioma (TBM) in a multicenter cohort. Study Design: Retrospective cohort study. Methods: Thirteen patients diagnosed with TBM at eight medical institutes between 1998 and 2018 were retrospectively enrolled. The clinical procedures, symptoms, signs, and images that led to the diagnosis of TBM were investigated for all patients. Results: The most common symptom at the initial visit was hearing loss (n = 12/13, 92.3%). All patients exhibited unilateral TBMs with varied symptom durations (1–60 months). Four patients presented masses occupying the external auditory canal; the tympanic membrane (TM) could not be evaluated. The other nine patients did not show TM perforation despite the presence of inflammatory signs. The majority of patients exhibited unilateral conductive or mixed hearing loss. A retrospective review of temporal bone computed tomography (TBCT) images revealed findings suggestive of a tumor in all patients. However, three patients had been misdiagnosed with chronic otitis media and were subjected to tympanomastoidectomy (n = 3/7, 42.9%). TBCT findings that suggested TBM included diffuse trabecular hyperostosis in the middle and posterior cranial fossae and widening and destruction of the temporal bone in the jugular bulb area. Conclusions: TBM should be suspected if patients exhibit persistent inflammatory symptoms or signs involving intact TM or unilateral conductive or mixed hearing loss with trabecular hyperostosis or destruction of the temporal bone on computed tomography images.
