Primary intracranial tumors generally occur as solitary tumors. The association of two primary intracranial tumors of different histogenesis in the same individual is rare, except in cases of phakomatoses or radiation-induced tumors. Meningiomas and vestibular schwannomas (VSs) are one of the commonest tumors occurring intracranially. VS account for 80% of cerebellopontine angle (CPA) tumors, with meningiomas being the second most common tumor of the CPA. The occurrence of both a schwannoma and a meningioma in the CPA is rare. We report a case with coexistent CPA meningioma and VS, which were distinct radiologically on preoperative imaging, however had admixed areas of VS and meningioma on histopathological evaluation.
