Brachioradial Pruritus Caused by Cervical Disc Herniation Precipitated by Trauma Treated with Anterior Cervical Discectomy and Fusion: Report of Two Cases and Review of the Literature

Brachioradial pruritis (BRP) is a rare form of dermatomal pruritis that appears to be caused both by cervical radiculopathy and exposure to ultraviolet-light, although the exact pathophysiology for the manifestation of these symptoms remains to be determined. A diagnosis of BRP is typically confirmed with the “ice-pack” test and evidence of cervical spine pathology using magnetic resonance imaging. Treatment options consist of application of ice, reduction in sun exposure, and topical capsaicin, antiepileptics, or tricyclic antidepressants. Patients with refractory symptoms and cervical spine pathology may be candidates for surgical decompression, particularly at the C5 and C6 levels. However, there are currently no established guidelines to treat BRP, or surgical procedures that have shown to be superior. Here, we report two cases of cervical disc herniations after traumatic events that presented as BRP. Both cases were successfully treated with anterior cervical discectomy and fusion with complete resolution of symptoms.
