Figure 5c.

PMP in a 57-year-old man. (a) Sagittal US image shows masslike expansion of the omentum with echogenic septa (arrow) surrounded by hypoechoic gelatinous fluid. The subjacent bowel loops are displaced centrally. (b) Axial contrast-enhanced CT image shows low-attenuation fluid surrounding the liver and displacing the stomach, with scalloping of the hepatic surface (arrow), which represents extrinsic pressure from the mucinous implants. (c) Coronal T2-weighted image shows scalloping of the intraperitoneal visceral surfaces (straight arrow) and heterogeneous signal intensity of the fluid (curved arrow), which allow differentiation of PMP from simple ascites.
