Meningioma Presenting As A Mass In The External Auditory

Meningiomas presenting as an intracranial neoplasm are relatively common. (15–18%).However, primary extracranial (ectopic, extracalvarial) meningiomas of the ear and temporal bone are rare, making up for less than 1% of all meningiomas. 1 The known female preponderance of intracranial meningiomas is also seen in the external auditory canal meningioma. They may be primary (very rare) or secondary due to extension of an intracranial meningioma.The possibility of a meningioma should be considered whenever a mass presents in the middle or external ear and a high index of suspicion is needed for diagnosis of such a condition, especially in view of a variety of differentials ranging from benign to malignant conditions.Computed tomography scanning is invaluable, not only for the diagnosis of this condition, but also to see the intracranial extent.
