Cholangiocarcinoma masquerading as liver abscess.
A 60-year-old man from Eastern Thailand was admitted to hospital because of right upper quadrant abdominal pain and fever. Ultrasonographic examination revealed two cavitary lesions in the right lobe of the liver. Needle aspiration obtained 110 ml of anchovy sauce-like pus which showed no bacteria on gram stain and routine culture. Serological test for E. histolytica antibody was negative. Initially, the patient responded well to metronidazole. Two weeks later, the symptoms recurred and sonography revealed one large cavitary lesion with three adjacent locules in the right lobe of the liver. Repeated needle aspiration again showed anchovy sauce-like pus which grew Enterobacter agglomerans. O. viverrini ova were detected in the stool. Laparotomy revealed histologically proven cholangiocarcinoma. This report indicates that O. viverrini infection associated with CCC can masquerade as liver abscess.
