Pitfalls and mimickers on 18F-FDG-PET/CT in peritoneal carcinomatosis from colorectal cancer: An analysis from 37 patients

Recommendations and consensus on the treatment of peritoneal metastases of colorectal origin: a systematic review of national and international guidelines

“…Retrospective studies assessing the value of PET/CT specifically for adequate staging of PMCRC (the second topic) suggest a superior sensitivity of PET/CT over CT, but numbers of patients are small and results remain inconclusive . Moreover, a false positive rate of 11% has been shown . Another increasingly applied imaging modality is magnetic resonance (MR) with diffusion weighted imaging (DWI).…”

Silk suture granuloma with false-positive findings on PET/CT accompanied by peritoneal metastasis after colon cancer surgery

“…In cases of colorectal cancer with positive postoperative PET/CT findings, the false-positive rate has been reported as 2–11% [1] , [2] , [3] . In addition to the PET/CT finding the elevated CEA levels, indicative of malignancy, led us to the decision for surgical intervention.…”

“…The sensitivity of PET/CT for colorectal peritoneal metastasis was reported to be 83–93% [3] , [14] , [15] , [16] . In patients diagnosed with distant metastasis in other organs, such as the liver, the probability of peritoneal metastasis has been reported to be up to 30% [17] .…”

FDG-PET/CT-Positive Foreign Body Granuloma Mimicking Colon Cancer Recurrence: Case Report

“…There are other cases in the literature describing lesions suspected of tumor recurrence in CRC by PET-CT scan, which proved to be benign only after histopathology study (Table 1) [14,[17][18][19][20][21][22][23][24]. …”
