Abstract:
Objective To investigate the CT imaging feature of EHCC associated with Clonorchiasis. Methods The CT image features of 18 patients with EHCC associated with Clonorchiasis proved by operation and pathology were reviewed retrospectively. Results CT depicited the level and cause of obstruction in all eigthteen patient. Most tumors( n =14,77.8%)were located in the proximal third of the extrahepatic bile duct. The gross morphologic pattern was an intraluminal soft tissue mass leision in 14 patients(77.8%), infiltrating in two patients and exophytic types in two patients. Contrast enhancement of the tumors relative to the liver parenchyma showed isoattenueation in 10 tumors(55.6%), hyperattenuation in seven tumors(38.9%) and hypoattenuation in one tumor(5.6%). Severe,uniform dilation of the intrahepatic bile duct was identified in 14 patients (77.8%) and central dilation was seen in four patients (23.2%).Male preponderance was found( n =15,83.3%). Conclusion It is concluded that the EHCC associated with Clonorchiasis is located predominantly in the proximal third of the extrahepatic bile duct and detected more readily than non Clonorchiasis-associated cholangiocacinoma.
