Preoperative Embolization in Intracerebral Meningiomas - Contradistinction: A Report of two Cases

The optimal treatment for intracerebral meningiomas is complete resection of the tumour, whenever possible, but this resection is often hindered by the hypervascularity of the tumour. Meningiomas being quite vascular, preoperative embolization can ease complete tumor resection by achieving devascularization of the tumour bed by initiating tumour necrosis by filling intratumoural vascularization by embolic material as far as the precapillary level and thus, diminishing operative time and intraoperative blood loss. The procedure is angiographically guided. We report the contradistinction in two cases of intracerebral meningiomas, one of which was preoperatively embolized while the other was not.
