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

View Article: PubMed Central - PubMed

ABSTRACT

Suture granuloma is relatively rare.

After tumor resection, positive PET/CT findings could indicate suture granuloma.

Postoperative PET/CT surveillance might give false-positive findings.

PET/CT cannot detect small peritoneal metastatic lesions.

A surgical examination should be performed when metastases are suspected.

A surgical examination should be performed when metastases are suspected.

No MeSH data available.

Diagnostic images.(a) CT showed a hepatic ring-shaped enhanced mass in S5/S8 (arrow). (b) FDG-PET/CT revealed a small focus of increased FDG activity in the liver (arrow). The maximum standardized uptake value (SUVmax) at the focus was 5.48. (c) Sonography revealed a halo around a hyperechoic lesion mimicking a "bull’s eye" sign (arrow). (d) Blood flow was confirmed in the tumor (arrow).

(d) Blood flow was confirmed in the tumor (arrow).

Mentions: At 4 postoperative months, surveillance computed tomography (CT) revealed a suspicious tumor at the hepatic resection stump (Fig. 1a). He was referred to our hospital for further examinations and treatments. Positron emission tomography/CT (PET/CT) revealed abnormal hepatic F-18 fluorodeoxyglucose (FDG) uptake below the diaphragm at the S5/S8 surface (SUVmax = 5.48; Fig. 1b). Sonography revealed a vascular lesion with a halo around a hyperechoic core (Fig. 1c and d). No other obvious lesions were seen.
