tract disease or intra-abdominal infections including cholecystitis, suppurative cholangitis, suppurative pylephlebitis, appendicitis, diverticulitis and peritonitis [1][2][3] . Recently, colorectal cancer without obvious infection was considered as one of the uncommon etiologies of liver abscess [4,5] . Furthermore, liver abscess was reported as the presenting manifestation of colonic tubulovillous adenoma [6] . However, there are a growing number of reports suggesting a relationship between diabetes mellitus (DM) and Klebsiella pneumonia (KP) liver abscess which indicate that a deficiency in the hosts' defense mechanism could be the etiology of this liver infection [7][8][9] . We hereby report two cases of pyogenic liver abscess both of which were found to have colonic tubulovillous adenoma two to three weeks later after the diagnosis of liver abscess. The association of pyogenic liver abscess and colonic tubulovillous adenoma and the implications of these two cases are discussed.
CASE REPORT
CASE 1A 67-year-old man, who was referred from a local hospital, was admitted to our hospital because of fever, chill, and right upper abdominal pain for seven days. On physical examination, his initial body temperature was 37.9 o C and blood pressure was 124/67 mmHg. Light palpation of the abdomen revealed tenderness and mild rebounding pain on epigastric and right upper areas, but no abdominal mass was felt. Significant laboratory data included a leukocyte count of 26,330/mL (normal range = 4000-10,400/mL ), a hemoglobin of 9.5 gm/dL (normal range = 12-16 gm/dL), an aspartate aminotransferase (AST) of 73 IU/L (normal range = 5-34 IU/L), an alanine aminotranferase (ALT) of 79 IU/L (normal range = 0-40 IU/L), a fasting blood sugar of 118 mg/dl (normal range = 70-110 mg/dL), a total bilirubin of 1.03 mg/dL (normal range = 0.2-1.3 mg/dL), a C-Reactive Protein (CRP) of 17.02 mg/dL (normal <0.8 mg/dL), and a carcinoembryonic antigen (CEA) level of 0.33 ng/dL (normal <5 ng/dL).Abdominal ultrasonography (US) and computed tomography (CT) showed a 4-cm liver abscess in left lobe of liver ( Figure 1A). After three sets of blood cultures were completed and broad-spectrum antimicrobial therapy was initiated, CT-guided percutaneous drainage of the liver abscess was performed and pus liked material was aspirated and sent for bacterial culture. However, blood and pus were all negative for bacterial growth. As antimicrobial treatment was continued, the patient's clinical condition improved rapidly and fever subsided four days

AbstractPyogenic liver abscesses usually occur in association with a variety of diseases. Rarely, liver abscess has been reported as the presenting manifestation of colonic tubulovillous adenoma. We report two cases of pyogenic liver abscess without hepatobiliary disease or other obvious etiologies except that one had a history ...
