Brachioradial Pruritus as a Harbinger of Syrinx in Chronic Spinal Cord Injury: A Case Report

This case describes a 56-year-old man with known thoracic spinal cord injury undergoing evaluation for a pruritic rash on the dorsolateral aspect of his forearms with no upper extremity neuromuscular symptoms. Common diagnoses were considered and treated with little success. The diagnosis of brachioradial pruritus (BRP) was made, and evaluation for possible causes revealed a large cervicothoracic syrinx. To our knowledge, BRP has not been described previously as the presenting sign of post-traumatic syringomelia. This patient's clinical course is delineated, as well as a brief review of BRP and its relationship to other cervical spine pathologies.
