The Utility of a Preoperative 3D Imaging Analysis System for Trigonal Meningioma.
Trigonal meningiomas are rare and pose surgical challenges due to their deep location and proximity to critical neuroanatomical structures. We present the case of a 67-year-old woman with a growing trigonal meningioma successfully resected with guidance by a preoperative 3D imaging analysis system. Integration of CT and MRI including diffusion tensor imaging (DTI) enabled precise mapping of the optic radiation, guiding a middle temporal gyrus approach. Preoperative embolization reduced tumor vascularity, facilitating gross total resection with minimal blood loss. This case highlights the effectiveness of preoperative 3D imaging systems in optimizing surgical planning and improving outcomes in complex neurosurgical cases.
