Case Report - Intradiploic meningioma of the orbit: A case report

We report a case of a 12-year-old male child who presented with a gradual onset exopthalmos involving the left eye. The plain radiographs of the skull showed hyperostosis of the left orbital roof. The computerized tomography (CT) scan revealed an intradiploic orbital roof tumor with expansion of both the tables of the orbital roof. The tumor was completely excised by an extradural route using a basal frontal craniotomy. The histopathological diagnosis of the tumor was a psammomatous meningioma. A split calvarial frontal bone graft was used to reconstruct the orbital roof. The pathogenesis, radiological features and surgical technique involved in the management of intradiploic orbital roof meningioma are discussed and the relevant literature is reviewed.
