Colorectal cancer causing abscesses in distant organs is rare. In this report, a patient with a liver abscess associated with ascending colon cancer causing intussusception is described. A 73-year-old woman presented with bloody stools. Colonoscopy showed ascending colon cancer. Blood tests at the initial visit showed severe inflammation and anemia. On contrast-enhanced computed tomography (CT), a low-density area was seen in the right lobe of the liver, and the patient was diagnosed with liver metastasis or liver abscess. Since antimicrobial therapy failed to improve the inflammation, a right hemicolectomy were performed. The patient was discharged after an uneventful postoperative course. Positron emission tomography showed a nodule in the right lobe of the liver with hyperaccumulation of fluorodeoxyglucose, which had markedly shrunk, leading to the diagnosis of liver abscess. On histopathological examination, the diagnosis was pStage IIIb, and CapeOX was initiated, though it was discontinued after one course. On one-year postoperative CT, no evidence of liver abscess or recurrence of colon cancer was seen. Colon cancer is a very rare cause of liver abscess. The cause of the liver abscess in this patient was presumed to be a transportal infection due to the intussusception secondary to colorectal cancer.
