(A,B) Contrast-enhanced MRI preoperatively indicated that the tumor was closely related to the internal carotid artery and A2 branch of ACA. (C) At POD3, MRI reexamination showed the degree of tumor resection. There was no tumor residue at the A2 branch of the ACA. Whether there was a small amount of tumor remaining at the right internal carotid artery (ICA) was not clear (red arrow). (D) This intraoperative image shows the tumor mass toughened by fibrosis and beyond the right ICA. (E) There was a close relationship between the A2 branch of the ACA and fibrosis-toughened tumors. (F) A few tumors were linked inextricably to the A2 branch of the ACA, and residual tumors were electrocoagulated repeatedly intraoperatively (red dotted circular box).
