Meningiomas involving the middle ear are rare. When these lesions are found, they usually represent an extension from an intracranial tumor.1 However, a meningioma can arise as a primary neoplasm of the middle ear, where it is thought to originate from arachnoid cells trapped during embryonic development.2 An affected patient usually presents with tinnitus, hearing loss, headaches, and, frequently, extreme otalgia.3 Facial nerve palsy may result from involvement by the tumor.3 Computed tomography and magnetic imaging are often helpful in making the diagnosis. These tests help determine if the tumor in the middle ear represents a direct extension from an intracranial tumor.4
