Temporal bone secretory meningioma presenting as a middle ear mass.
A 44-year-old woman presented with a history of increasing left hypoacusis and sporadic vertigo. CT scan revealed a tumor occupying the mastoid, middle ear, and external auditory canal. After surgical removal, a typical secretory meningioma was diagnosed. The histological hallmark and the immunohistochemical profile of secretory meningiomas are reviewed. The differential diagnosis of this tumor in this location is also commented on. As far as we know, primary temporal bone meningiomas with secretory histology have not been previously reported in the medical literature.
