Temporal meningiomas presenting as chronic otitis media.

Two cases of temporal bone meningiomas presenting as chronic drainage ears are presented. One case was indicated by computer tomographic scan at the time of initial surgery to be limited to the middle ear, but recurred 9 months later with extensive cerebellopontine angle extension and cranial nerve palsies. The tumor in the second case extended from the middle ear to the cavernous sinus, with extensive intradural involvement. Meningiomas involving the middle ear must be considered to have intracranial extension, and magnetic resonance is the imaging study of choice.
