A rare case of compartmentalized presentation of extradural meningioma

Meningioma is a common benign intracranial neoplasm. The incidence of its extracranial extension is rare. Of the meningioma types, meningothelial variety is the most common histological type. Authors report a case of compartmentalized presentation of extradural meningioma in a 35-year-old male who presented to us with a frontal region swelling (exostosis). The patient was evaluated with computed tomography scan of the brain. At surgery, he was found to have compartmentalized presentation of the scalp, calvarium, and dura which we would like to report in this case.
