Abstract:

Meningiomas are the second most common tumors in the cerebellopontine angle (CPA) . They rarely enter or originate from the internal auditory canal (IAC) . Primary meningiomas of the internal auditory canal (IAC-M) originate from the dura mater in the IAC. The main body of the tumors is in the IAC, which belongs to the special type of meningiomas of the CPA. Most of them are reported in individual cases. Simple intra-auditory meningiomas have not been proposed as an independent class in classification because of their rarity. Primary intra-auditory meningioma is not only a challenge to the diagnosis of neuroradiology, but also a difficult problem for neurosurgeons. This paper summarizes and analyses the clinical and imaging features and the origin of IAC-M reported in the literature, with a view to preliminarily describing the clinical, radiological and surgical specificities of IAC-M, so as to provide a basis for the selection of appropriate treatment options for IAC-M.

Key words: Cerebellopontine angle, Internal acoustical canal meningiomas, Neuroimaging
