Abstract

Intracranial angiomatous meningiomas are a rare WHO grade I histological variant of meningioma whose vascular component exceeds 50% of the total tumor area. Preoperative embolization of angiomatous meningiomas has rarely been reported previously. A 58-year-old woman was referred to our institute for a large petrotentorial hypervascular tumor presented with progressively worsening right facial paralysis and hearing loss for 6 months. Cranial computed tomography scan and magnetic resonance imaging revealed a large homogenously enhancing multilobulated mass involving middle and posterior cranial fossae with marked brainstem compression. The tumor extended into a right internal auditory canal and labyrinthine structures with destructive changes of bony structures. Magnetic resonance angiography showed hypervascularity in the tumor. Preoperative transarterial embolization using liquid embolic materials was successfully performed with resulting in almost complete devascularization of the tumor. Adequate hemostasis was achieved following gross total resection of the tumor (Simpson grade II). A histopathological examination confirmed the diagnosis of an angiomatous meningioma. Preoperative transarterial embolization of angiomatous meningioma with liquid embolic material was safe and effective in reducing perioperative blood loss and facilitating total tumor resection.
