Risk factors for nonresolving neurological deficits after spinal meningioma surgery: an integrated clinical and volumetric analysis of 202 patients.

This volumetry-informed series of patients with SM revealed older age and a low Ki-67 index, along with preoperative neurological deficits, constitute a higher risk of nonresolving neurological symptoms after resection. An early surgical intervention in oligosymptomatic young patients could therefore help preserve excellent long-term neurological function.
