A 10-year-old female patient with central skull base meningioma invading the paranasal sinuses. A 10-year-old female patient with central skull base meningioma invading the paranasal sinuses. Axial postcontrast T1WI demonstrates an enhancing mass within the central skull base. The mass involves the ethmoid and sphenoid sinuses and was a biopsy-proved meningioma. Nonenhancing anterior portion of the sphenoid sinus is filled with secretions (black arrow). Multiple additional schwannomas are seen in the Meckel cave and the internal auditory canal (white arrows) in this patient with neurofibromatosis type 2. Although meningioma is common in adults, in pediatric patients, the lesion is much rarer and occurs in the setting of neurofibromatosis type 2 or prior radiation therapy. Y.W. Lui et al.
