FIG. 14.16 Peritoneal Carcinomatosis From Mucinous Adenocarcinoma, Presumably of Gastrointestinal Origin. (A) Transverse transabdominal

pelvic sonogram and (B) CT scan at the same level show ascites and bilateral ovarian solid masses (O) suggestive of Krukenberg tumors. The

marked complexity of the luid with particles and septations is better appreciated on the ultrasound scan (arrows in A). (C) Transverse midabdominal

ultrasound image and (D) corresponding CT scan show a thick “omental cake” (arrows) displacing bowel loops posteriorly in the peritoneal cavity.

Free luid is also visualized. (E) Oblique ultrasound image in the right upper quadrant shows a rim of complex, mixed-echogenic material overlying

and indenting the convexity of the liver (arrow). There is echogenic nodularity on the parietal peritoneum of the diaphragm. This did not move with

the liver on respiration, conirming its origin from the parietal peritoneum. (Reproduced from Wilson SR. Pseudomyxoma peritonei. In: Cohen HL,
