Figure 4. (A) Simple computed tomography (CT) showing a prominent mass (red arrow) in hepatic S8 and ascites (yellow arrow) with high CT values. (B) Simple CT showing numerous disseminated lesions (red arrows) in the abdominal cavity. (C, D) In the diaphragm, numerous lumpy tumors (red arrows) and disseminated nodules (red arrows) up to 13 cm in size, adherent to the right lobe capsule of the liver, are observed. A 3-cm large mass (yellow arrow) that is exposed on the surface of the liver S8 is observed. A clot is also observed near the right subdiaphragm.
