56-year-old female with surgically unresectable pancreatic adenocarcinoma presented with intractable abdominal pain which was unresponsive to maximum pain palliation. The patient was planned for CT-guided celiac plexus neurolysis. (a) Axial non-enhanced CT image demonstrates pancreatic mass lesion (arrowhead) and the anterior approach to celiac plexus with 20G needle (arrow) in the supine position. (b) CT image acquired after contrast material injection showed the optimal location of the needle (arrow) before alcohol injection. (c) Axial non-enhanced CT image obtained from another patient demonstrates placement of needle (arrow) with posterior paravertebral approach.
