Meningiomas with transosseous extension provide opportunities for extensive preoperative embolization, through conventional trans-arterial approaches, and also through less commonly used percutaneous methods. This video demonstrates embolization of a 7.6 × 9.5 × 9.9â
cm transosseous WHO grade II meningioma.1 Trans-arterial embolization was conducted via the left middle meningeal, occipital, and superficial temporal arteries. Only one superficial temporal artery was embolized to preserve vascular supply to the skin flap. To further devascularize the tumor, concomitant percutaneous embolization was performed. Transosseous extension of the tumor facilitated extensive percutaneous embolization of both the intracranial and extracranial components of the mass. Intraoperative bleeding from the scalp and extracranial component of the tumor was minimal. The intracranial tumor was soft and necrotic and was removed with suction and gentle dissection. Residual tumor was left behind within and adjacent to the superior sagittal sinus. The patient recovered without neurological deficit and was referred for radiation of the residual tumor.
