초록
The meningiomas are slowly growing tumors arising from meningoepithelial cells and they generally occur throughout the craniospinal axis. Meningiomas extending to the middle ear cavity are uncommom and these patients complain of otologic symptoms such as hearing loss, ear fullness, or otorrhea. Clinical findings frequently suggest otitis media resistant to conventional treatments, thereby facilitating misdiagnosis. CT and MRI of the temporal bone are essential and important for the radiologic differential diagnosis with other tumors. The ideal treatment of these tumors is a total surgical removal. In this report, we describe 2 cases of middle ear meningioma originating from middle and posterior cranial fossas with a review of the literatures.
Abstract
The meningiomas are slowly growing tumors arising from meningoepithelial cells and they generally occur throughout the craniospinal axis. Meningiomas extending to the middle ear cavity are uncommom and these patients complain of otologic symptoms such as hearing loss, ear fullness, or otorrhea. Clinical findings frequently suggest otitis media resistant to conventional treatments, thereby facilitating misdiagnosis. CT and MRI of the temporal bone are essential and important for the radiologic differential diagnosis with other tumors. The ideal treatment of these tumors is a total surgical removal. In this report, we describe 2 cases of middle ear meningioma originating from middle and posterior cranial fossas with a review of the literatures.
