Epi-Arachnoidal Drug Deposit Günter Ochs, MD, PhD, Ralf Giess, MD, Markus Bendszus, MD, Andreas Krone, MD, PhD Journal of Pain and Symptom Management Volume 18, Issue 3, Pages 229-232 (September 1999) DOI: 10.1016/S0885-3924(99)00067-6
Fig. 1 (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) Journal of Pain and Symptom Management 1999 18, 229-232DOI: (10.1016/S0885-3924(99)00067-6)
