Conjoined nerve root: case illustration

AbstractConjoined nerve roots are an infrequent and uncommon finding, rarely noted preoperatively. The conjoined root anomaly has potential for significant neurological injury during surgery. Preoperative recognition may avert disastrous nerve root injury but requires a high degree of clinical suspicion. We present the case of a 44-year-old patient with left L5/S1 radiculopathy caused by a herniated disc. During surgery we identified a triple conjoined nerve root anatomy. This anatomical variant, to our knowledge, has not been reported in literature. We describe the anatomical findings and surgical implications.

Conjoined Nerve Root

✓ A case of a nerve root anomaly in a patient presenting with cervical radiculopathy is presented. The patient was treated with posterolateral exploration and decompression, resulting in relief of pain and improvement in strength. Both the preoperative contrast-enhanced computerized tomography scan and the magnetic resonance image demonstrated an abnormality behind the C-4 body extending from the right C3–4 neural foramen to the neural foramen at C4–5. At surgery, a dural-encased structure was discovered connecting the C-4 and C-5 nerve roots within the spinal canal. This paper describes the first reported case of a cervical nerve root anomaly of this type, representing a variant of a conjoined nerve root. The occurrence of such nerve root anomalies in the cervical spine should be entered into the differential diagnosis and treatment of cervical radiculopathy.
