A Case Report of a CPA Meningioma Presenting as Middle Ear Mass With Middle Ear Effusion.

Middle ear (ME) benign tumors are rare, and among them is meningioma. An ME meningioma might be isolated or merely a lateral extension of a CPA meningioma. We report a case with presentation of ME effusion followed by the appearance of an aural polyp after repeated myringotomies. Computed tomography (CT) revealed a benign-looking ME and mastoid mass. After debulking and biopsy, it turned out to be a meningioma. However, when MRI was performed, a large CPA meningioma was detected. ME masses are rare; however, they might be encountered, and CT must be performed followed by biopsy or total removal. In case of detection of a tumor with probable intracranial connection as meningioma, an MRI should be performed to exclude intracranial extension.
