World Journal of Surgical Oncology 2011 9 28 http content 9 1 28 WORLD JOURNAL OF SURGICAL ONCOLOGY CASE REPORT Open Access A role of 18F-fluorodeoxyglucose positron emission computed tomography in a strategy for abdominal wall metastasis of colorectal mucinous adenocarcinoma developed after laparoscopic surgery Kimihiko Funahashi Mitsunori Ushigome Hironori Kaneko Abstract Metastasis to the abdominal wall including port sites after laparoscopic surgery for colorectal cancer is rare. Resection of metastatic lesions may lead to greater survival benefit if the abdominal wall metastasis is the only manifestation of recurrent disease. A 57-year-old man who underwent laparoscopic surgery for advanced mucinous adenocarcinoma of the cecum 6 years prior developed a nodule in the surgical wound at the lower right abdomen. Although tumor markers were within normal limits the metastasis to the abdominal wall and abdominal cavity from the previous cecal cancer was suspected. An abdominal computed tomography scan did not provide detective evidence of metastasis. 18F-fluorodeoxyglucose positron emission computed tomography 18F-FDG PET CT was therefore performed which demonstrated increased 18F-fluorodeoxyglucose uptake maximum standardized uptake value in the small abdominal wall nodule alone. Histopathological examination of the resected nodule confirmed the diagnosis of metastatic mucinous adenocarcinoma. Prognosis of intestinal mucinous adenocarcinoma is reported to be poorer than that of non-mucinous adenocarcinoma. In conclusion this case suggests an important role of 18F-FDG PET CT in early diagnosis and decision-making regarding therapy for recurrent disease in cases where a firm diagnosis of recurrent colorectal cancer is difficult to make. Background Metastasis to the abdominal wall including port sites after laparoscopic surgery for colorectal carcinoma CRC is rare. Recently the rate was reported as in a randomized clinical trial .
