Abstract
We report a case of sigmoid colon cancer presented with multiple liver abscesses in the bilateral lobes. A 46-year-old man was seen at the hospital because of fever up and right hypochondralgia. Computed tomography and ultrasonography of the abdomen revealed multiple liver abscesses. The patient submitted well to the administration, and the treatment with antibiotics was immediately started. Colonoscopic examinations to explore the cause of these liver abscesses revealed sigmoid colon cancer. A biopsy resulted in well differentiated adenocarcinoma. Inflammatory reaction subsided and the liver abscesses diminished with antibiotics. Because no findings suggestive of liver metastasis was seen, sigmoidectomy with lymph node dissection (D3) was carried out. Histopathological findings showed tub1, ss, n1, ly2, v1, and Stage IIIb. The patient has been free from liver metastasis and liver abscesses one year after the operation. It was etiologically inferred that multiple pyogenic liver abscesses might be caused by colon cancer through the portal route, but we could not identify the mechanism why the bilateral hepatic lobes were infected. In the diagnosis and treatment of hepatic abscesses, complete gastrointestinal examinations would be needed by keeping a possibility of colon cancer as a causative disease for liver abscesses in mind.
