Surgically proven infiltrative mucinous gastric carcinoma in a 45-year-old man. Coronal contrast CT reveals diffuse low attenuation thickening of the gastric wall with punctuate calcifications (arrows). The thin high-attenuating inner layer (arrowhead) is preserved while the middle and outer layers show low density thickening; this along with the punctate calcifications favours mucinous adenocarcinoma. Inset: image at the level of the pelvis reveals bilateral complex solid cystic masses (arrows) consistent with ovarian metastases or Krukenberg tumours. Mucinous gastric carcinoma is a rare subtype of gastric carcinoma and has a poorer prognosis than other subtypes.
