Long-term survival of a patient with colorectal cancer with peritoneal carcinomatosis and low completeness of cytoreduction score: A case report

Figure 1 Moderate to large volumes of diffuse ascites in the abdominal and pelvic cavities, with smudged, nodular omentum extending from the epigastric region to the lower abdomen. A: Coronal image; B: Peritoneal, seeding, nodular, mass lesions thickening in the cul-de-sac area, with focal abutment or invasion of the anterior wall of the mid-rectum; C: Sagittal view.

Figure 2 Colonoscopic features. A: Ulcerofungating mass, 4 cm in diameter, was observed 45 cm from the anal verge during preoperative colonoscopy; B: Complete removal of the primary tumor was noted upon follow-up colonoscopy.

Figure 3 Positron emission tomography-computed tomography of the patient’s abdomen and pelvis. A: Extensive hypermetabolic activity throughout the mesentery and omentum, suggesting diffuse peritoneal metastasis; B: Increased metabolic uptake in the pelvic region, indicating likely peritoneal seeding in the pelvic cavity.

Figure 4 No sign of recurrence or metastasis is observed in either image. A: Postoperative day 525; B: Postoperative day 2164.
