Cavernous Sinus Meningioma of the Oculomotor Nerve in a Child: A Surgical Case Study

Abstract

AbstractPediatric cavernous sinus meningiomas are rare. Herein, we present the case of a 5-year-old boy who presented with progressive left oculomotor nerve palsy. A head magnetic resonance imaging revealed a mass lesion in the left cavernous sinus, following which tumor resection was performed. The tumor strongly adhered to the left oculomotor nerve without adherence to the walls of the cavernous sinus; however, its border with the nerve was unclear. Histopathological analysis led to the diagnosis of fibrous meningioma. To the best of our knowledge, this is the first case study to report the pediatric development of a cavernous sinus meningioma in the oculomotor nerve.
