Treatment of a Patient With Meningioma With Complicated Blood Supply.

Meningiomas account for ~30% of primary intracranial tumors, making them the second most common type of brain tumor. Most meningiomas are benign, and surgical resection is curative. By utilizing 3-dimensional slicer technology for multimodal image fusion, a wealth of 3-dimensional anatomic information can be obtained, enabling more effective treatment of meningiomas with complex tumor locations and surrounding structures. Guided by the 3-dimensional structural models, we conducted detailed preoperative planning for 1 case of highly vascularized meningioma and utilized combined surgery for complete tumor removal, effectively avoiding intraoperative bleeding and postoperative complications.
