Figure 4.

CE-axial CT scan of the abdomen and pelvis, in a 32-year-old female patient, shows extensive peritoneal metastasis from the GIST and subcutaneous deposits obscuring the origin. (a) Multiple, solid, enhancing deposits are noted on both sides of the pelvis, abutting the uterus and rectum (open arrow); the white solid arrow indicates subcutaneous deposits. (b) Multiple omental deposits (open arrows) show heterogeneous enhancement; their origin is obscure. (c) Two discrete deposits in the liver show solid (white solid narrow arrow) and cystic (open wide arrow) components on a contrast-enhanced scan.
