Abstract

Meningiomas are benign extraaxial tumors of the central nervous system (CNS). Extracranial meningiomas are extremely rare (2%) and can develop as a direct extension from a primary intracranial meningioma or as true primary extracranial meningioma originating from ectopic arachnoid cells. Only eight cases of primary meningioma in the jaw have been reported to date. Extracranial meningiomas are frequently misdiagnosed, resulting in inappropriate clinical management. The aim of this article was to describe the case of a man with an asymptomatic swelling in the right retromolar area over a period of 2 months. Cone beam computed tomography was performed to determine the extension and involvement of the adjacent structures. Histopathological findings and immunohistochemical analysis aided in the diagnosis of primary extracranial meningioma in the mandible and several aspects of this unusual neoplasm are reviewed. The treatment of choice was a partial resection of the mandible and reconstruction with autogenous iliac tricortical bone. Five years after surgery, the patient remains free of disease.
