- Fig 1.
Images in a patient with a left C6 radicular pain due to posterolateral disk herniation. Pain was completely relieved after infiltration and sustained at clinical follow-up 6 months.
A, Postcontrast CT image at the C5-C6 level shows the vertebral artery (arrowhead) in front of the spinal ganglion (white arrow) and the soft posterolateral disk herniation (black arrow).
B, Needle in contact with the foraminal site of the nerve root (arrow).
C, Control CT scan after foraminal contrast injection shows contrast medium around the spinal ganglion (arrow).
