Total removal of anaplastic meningioma infiltrating an artery by performing an A3-A3 side-to-side anastomosis.

ABSTRACT:

Background

Meningiomas are histologically benign tumors and generally have a good prognosis. However, some are classified as high-grade meningiomas due to their strong invasion of surrounding tissues and high postoperative recurrence rates, resulting in a poor prognosis. Postoperative radiotherapy is often administered for the most malignant anaplastic meningiomas; however, its contribution to improving prognosis and reducing recurrence rates in patients with residual tumors is limited.

Case description

We present here a 48-year-old man with an anaplastic meningioma that recurred repeatedly and had invaded the right anterior cerebral artery (ACA) despite two postoperative radiotherapy sessions. Dissecting the tumor from the blood vessels was extremely difficult and would onl
