1. Patient presentation

  • A 76-year-old woman reported abdominal pain that had started 3 months earlier.
  • Her medical history included gastrectomy and chemotherapy for gastric cancer.
  • Laboratory tests indicated elevated levels of CEA, but other values were normal.
  • Conventional colonoscopy was incomplete at a distance of 100 cm from the anal margin because of
    poor bowel preparation. No pathological findings were reported except for proctitis.

  • Contrast-enhanced CT colonography was performed for further investigation.
  • Histological analysis of the colonic surgical specimen revealed signet ring cell carcinoma.
