    Small intratumoral calcifications are often seen within meningioma, but ossification of the whole neoplasm is very rare. The case of an ossified frontosphenoorbital meningioma en plaque is presented. The radiological appearance resembled extensive hyperostosis extending from the anterior clinoid process to the cerebral convexity and falx cerebri. It is possible that, in some cases of meningioma, the identified "hyperostosis" represents partial ossification of the tumor itself.
