Late recurrence of spinal neuri- noma after its single-stage total removal

Abstract

Dumb-bell schwannomas (neurinomas) account for 15 % of the total number of spinal neurinomas. Their surgical removal in the cervical spine is a technical challenge due to intricate anatomical relationships. The paper presents a clinical case of recurrence of the dumb-bell neurinoma at the cervicothoracic level 20 years after its total single-stage removal. The tumor recurrence was confirmed by the data of neuroimaging monitoring. Repeated removal was performed. The paper describes in details the course of the disease, clinical and radio- logical manifestations, and results of neurophysiological monitoring.
