Spinal Nerves Schwannomas: Experience on 367 Cases—Historic Overview on How Clinical, Radiological, and Surgical Practices Have Changed over a Course of 60 Years

Figure 3

Illustrative case. A 61-year-old man presenting with anesthesia on the anterior portion of the right leg. (a) Preoperative MRI, sagittal sequence; (b) preoperative MRI, axial sequence. The patient underwent surgical intervention with NPhM; the schwannoma was found to have strict adherence with a sensitive root and to arise from a motor root; intraoperative stimulation showed high activation pattern of L4 (see video). Schwannoma was removed carefully and preservation of the nerve root was obtained. Postoperative course was uneventful.
