Abstract
Meningiomas are tumors that arise from arachnoid cells attached to both the pia mater and the inner portion of the arachnoid. They are common intracranial tumors, representing 12-25% of intracranial neoplasms. Intracranial meningiomas can spread extracranially to involve surrounding structures, including the ear and temporal bone. Ectopic meningiomas, described as primary meningiomas with no intracranial involvement, are rare. We describe a case of a primary external auditory canal meningioma with no evidence of intracranial involvement. We present pre-operative imaging findings proving no intracranial involvement prior to surgical intervention. A literature review of this uncommon clinical entity is presented and a discussion regarding its prognosis and treatment is reviewed.
