Abstract A basic understanding of audiologic testing and the physical principles of hearing allows radiologists to leverage relevant clinical information and audiologic test results to interpret temporal bone imaging accurately, especially temporal bone CT in the setting of conductive hearing loss. The standard of reference for diagnosing and characterizing hearing loss is audiologic testing.

1. IntroductionMeningiomas are the second most common intracranial tumors and make up 15% - 20% of all primary brain tumors [1]. However, meningiomas of the middle fossa floor that extend into the middle ear are exceedingly rare [1]. These are extracranial meningiomas and make up about 1% - 2% of all meningiomas [2]. They often have extension secondary to the primary intracranial tumors and accompany osteolytic change of the skull [3]-[5].
