  ABSTRACT: This is a case of a 60-year-old male with a history of prior left middle fossa meningioma that was partially resected with an operative report noting diffuse attachment to the middle fossa floor. Gamma knife was recommended but he never completed this management. He then presented about eight years later with a mass from his left external auditory canal. It was reported that two years prior another surgeon operated on the left ear for a cholesteatoma. CT temporal bone showed complete opacification of left EAC, mastoid bowl, and remaining mastoid air cells. In addition, there were irregular bony/hyperostotic changes seen within the left sphenoid and temporal bone. There was dural thickening within the middle fossa adjacent to the previously described hyperostotic bony changes. A mastoidectomy and excision of mass revealed extensive adhesive tissue throughout the middle ear, and mastoid up to the tegmen. Pathology of the portions that were resected confirmed Grade 1 meningioma. Stereotactic gamma knife radiation was completed to the area to prevent further growth. This case highlights extracranial meningioma that did not have definitive management for prior middle fossa floor meningioma. It also highlights the need to think of less common pathology in the middle ear and external auditory canal.
