Abstract
A 62-year-old man was found to have rectal tumor at another hospital and he was admitted to our hospital. Computed tomography (CT) showed S5 and S7 tumors were irregular and peripheral enhanced. Fluorodeoxyglucose positron emission tomography (FDG-PET) showed uptake in the S5 tumor, but no uptake in the S7 tumor. Under a diagnosis of rectal cancer with liver metastasis, we performed segmentectomy of the S5 and partial resection of S7 following Milesʼ operation. Histological examination revealed that rectal cancer was moderately differentiated adenocarcinoma and the liver tumors were inflammatory pseudotumor. The patient is alive with no signs of recurrence 6 years after surgery. It is important that differential diagnosis between hepatic inflammatory pseudotumor and liver metastasis when the patient has malignant disease. We report a case of hepatic inflammatory pseudotumor with rectal cancer.
