(a) Unenhanced transversal T1-weighted image (SE, TE 495, TE 15) at the level of T9 demonstrates a hyperintense formation at the dorsal aspect of the dural sac. (b) Lateral X-ray of the upper lumbar spine after injection of contrast medium in the pump side port reveals an epi-arachnoidal deposit of contrast medium (open arrow) cranial of the catheter tip (closed arrow). (c) Spinal CT at the level of T 8–10 shows contrast medium between the arachnoidal and dural sheath of the meninges (open arrow) cranial of the catheter tip (closed arrow)
