It is a difficult problem in neurosurgery to completely resect motor area tumors without leaving motor deficits. The key to the surgery is the preoperative and intraoperative precise localization of the motor area and cone bundle and the fine surgical technique. The precise localization of the tumor in the motor area by cranial MRI and meticulous surgical technique can completely resect the tumor in the motor area without damaging the motor function. The picture of a typical case illustrates that the slightly high signal (gray) shown by the red arrow is the tumor before surgery; the high signal (white) shown by the green arrow is the operative cavity after surgery. The tumor was completely resected, and the muscle strength was reduced in the short term after surgery, and returned to normal completely in 2 weeks.
