Abstract

Clonorchiasis, known as the parasitic fluke in the intrahepatic bile ducts, occurs throughout Korea, Japan, Taiwan, and Vietnam with high frequency. Most of the infections follow the consumptions of raw or undercooked freshwater fish, which explains its rare occurrence to childhood even in those areas mentioned earlier above. The authors have experienced it with an 8 year old boy. Abdominal ultrasonogram revealed multiple low echogenic nodules in the right lobe of liver and lymph nodes proliferation around the porta hepatis area. And abdominal C.T. scan also found multiple low attenuated nodules with delayed enhancement in liver parenchyma with hepatomegaly and multiple conglomerated lymph nodes in porta hepatis. Both abdominal ultrasonogram and C.T. scan didn't show any dilatation of peripheral intrahepatic bile ducts. In repeated stool examination, Clonorchis sinensis eggs were found in feces and the result of the skin test for Clonorchis sinensis was positive. The patient had a history of having eaten raw pond smelt back in Cheongju a month before the symptom onset. On the basis of the patient's history and the fact that Clonorchis eggs were found in feces 3 weeks after eosinophilia and symptoms were noted, the authors estimated that the findings of the patient's abdominal sonogram and C.T. scan were the radiologic findings of the acute phase of clonorchiasis, of which no report had ever been made before. So the authors report a case of clonorchiasis with atypical radiologic findings in an 8 year old boy.
