Pseudomyxoma peritonei shown on multiple axial fused FDG PET-CT images. Spillage or seeding of mucinous material from either mucinous cystadenomas or cystadenocarcinomas of the pancreas (as well as breast, ovary, colon and appendix) can result in gelatinous ascites (white arrowheads) that will spread and grow throughout the abdomen. Shows is a case with (a) Mucinous material in the gallbladder fossa and implanted on the stomach (a,b); (c) Infiltrating mucinous implants caking the omentum; and (d) Mass-like mesenteric implants.
