The right C5, C6 and C7 roots (especially C5) are thickened beyond their dorsal root ganglia. There is buckling of these nerves (trunks) posterior to the clavicle. The thickening and buckling also extends laterally into at least one of the cords. The dorsal root ganglia have normal appearances. There is no "pseudo-meningocoele". The central vertebral canal and neural exit foramina and capacious. The cervical spinal cord shows normal signal.There are prominent lymph nodes in the neck bilaterally. These are larger on the left, for example level IIa (18 x 11 mm axially) and Vb (12 x 11 mm).
Conclusion: Thickening and buckling of the right C5, C6 and C7 roots. The roots are intact, however. The findings are thought to represent previous traction injury. Incidental cervical lymph node enlargement, which warrants clinical correlation in the first instance.
