Radiologic Findings of Dorsal Root Entry Zone Lesioning

Dorsal root entry zone lesioning is an intervention that may be performed in patients with brachial plexus avulsion injuries to reduce neuropathic pain. There is little description in the literature of the expected postoperative imaging findings following dorsal root entry zone ablation. We describe a case of a 36-year-old man who underwent MR imaging of the cervical spine 3 years following dorsal root entry zone lesioning. This article will also discuss the expected postoperative imaging findings following dorsal root entry zone lesioning as well as the imaging features of common complications of the procedure.
