Liu, a 64-year-old man living in Putuo District, Shanghai, had been suffering from dizziness for the past half month, and his symptoms were mild at first, so he did not pay attention to them, but later on, his dizziness increased significantly and he went to our neurosurgery department. Preoperative evaluation: The diagnosis of paraganglioma of the sagittal sinus was clear, and the only treatment at present was surgery. Since it is a meningioma, located in the motor area with abundant blood flow, surgery is extremely risky and difficult. It is mainly reflected in three aspects: Firstly, the tumor is huge, with obvious occupying effect and neurological damage symptoms, and it is located next to the falx cerebri, with obvious adhesions to the sagittal sinus and brain tissue, which makes the operation time long and traumatic. Secondly, the tumor is rich in blood flow and the texture will be hard, so there will be many difficulties in separating and stopping the bleeding of the tumor, and it is often difficult to completely remove the tumor; thirdly, the tumor is close to the motor center, so it is very easy to damage the motor center and cause postoperative paralysis during surgery. Preoperatively, we explained the condition with the patient’s family, and the patient’s family firmly requested the surgery. Preoperative MR: Microscopic craniotomy for perfect removal of tumor In the morning of June 19, after thorough preoperative preparation, Dr. Li Xinyuan, director of neurosurgery, operated personally. The tumor was seen to be hard and tough, rich in blood flow and closely adhered to the cerebral falx. While separating the tumor, we protected the surrounding brain tissues with cerebral cotton sheets and gradually controlled the blood supply vessels of the tumor. The patient recovered well after the operation, and the dizziness symptom improved significantly without any after-effects, and the limb activity was completely normal. Post-operative review of CT tumor total resection.
