title: Meningiomas of the anterior skull base expanding into the orbit, paranasal sinuses, nasopharynx, and oropharynx.
abstract: The natural progression of the infiltrative anterior skull base meningioma, expanding into orbit, paranasal sinuses, nasopharynx, and oropharynx during 12 years is presented. The development of the lesion is demonstrated on computed tomography. The patient was operated on six times from the age of 14. Pathological investigation revealed infiltrative meningoteliomatous meningioma without signs of malignancy.
