Background: Oriental Cholangiohepatitis (Clonorchis infestation) is caused by Clonorchis sinensis, a liver fluke endemic to China. Objective: To discuss the presentation of clonorchiasis and diagnosis of this condition in the emergency department (ED). Case Report: This is a case report of a Chinese woman who recently immigrated to the United States and was evaluated in a tertiary care urban ED. The patient presented with complaints of abdominal pain and was found on imaging to have clonorchiasis infestation of the bile ducts. She was admitted and treated for cholangitis and clonorchiasis infestation with piperacillin/tazobactam and praziquantel. Conclusion: History and imaging play an important role in diagnosis of this endemic parasitic abdominal infection.

Carcinoma of the gallbladder associated with clonorchiasis: clinicopathologic and CT evaluation

BACKGROUND: The computed tomographic (CT) features of three cases with pathologically proven adenocarcinoma of the gallbladder associated with clonorchiasis. METHODS: CT scans of three cases with pathologically proven adenocarcinoma of the gallbladder associated with clonorchiasis were retrospectively reviewed. Scans were analyzed for the following parameters: (a) gross morphologic pattern (intralumenal mass lesion, mass replacing the gallbladder, focal or diffuse wall thickening); (b) contrast enhancement of the tumors; (c) associated gallstones or Chlonorchis sinensis worms; (d) direct invasion into the liver; (e) metastasis to adjacent viscera (pancreas, duodenum); (f) the extrahepatic bile duct (dilatation, metastasis, stone, C. sinensis worms); (g) the intrahepatic bile duct (dilatation); and (h) lymphadenopathy and metastasis. RESULTS: The gross morphologic pattern of three cases with carcinoma of the gallbladder was an intralumenal mass lesion (the least common type), whereas the patterns of infiltration and a mass replacing the gallbladder were not identified. Mild contrast enhancement of the tumors relative to the liver was demonstrated in all patients. Gallstones and C. sinensis worms were not visualized in the gallbladder and the extrahepatic bile duct. An unusual metastasis to the distal common bile duct and the pancreas was found in this series. CONCLUSION: Three cases with adenocarcinoma of the gallbladder associated with clonorchiasis showed intralumenal mass lesions within the gallbladder lumen. The cause-and-effect relation between clonorchiasis and gallbladder carcinoma is discussed.     

Extrahepatic cholangiocarcinoma associated with clonorchiasis: CT evaluation

BACKGROUND: I evaluated the computed tomographic (CT) features of nine pathologically proven cases of cholangiocarcinoma in the extrahepatic bile duct associated with clonorchiasis. METHODS: CT scans of nine pathologically proven cholangiocarcinoma associated with clonorchiasis were reviewed retrospectively. CT scans were analyzed for the following parameters: tumor (detection, location, gross morphologic type, contrast enhancement), intrahepatic bile duct (dilatation, pattern of dilatation), common bile duct (dilatation, Clonorchis sinensis worms), gallbladder (inflammation, C. sinensis worms), invasion of the contiguous viscera (pancreas, duodenum, liver), lobar atrophy, and lymphadenopathy and metastasis. RESULTS: CT depicted the level and cause of obstruction in all nine patients (100%). Contrast enhancement of the tumors relative to the liver parenchyma showed isoattenuation in five tumors (55%) and hyperattenuation in four tumors (44%). Severe, uniform dilatation of the intrahepatic bile duct was identified in six patients (67%) and central dilatation was seen in two patients (22%). No evidence of dilatation of the intrahepatic bile duct was seen in one patent (11%). Most tumors were located in the proximal third of the extrahepatic bile duct ( n = 7, 78%). Male preponderance was found ( n = 8, 89%). CONCLUSION: Cholangiocarcinoma associated with clonorchiasis was located predominantly in the proximal third of the extrahepatic bile duct and detected more readily than nonclonorchiasis-associated cholangiocarcinoma.

目的探讨作者华支睾吸虫致胆道阻塞的影像表现及诊断价值。方法对经实验性感染华支睾吸虫的犬,依感染数量和观察时间的不同,分别进行实验病理、B超、CT的同步观察。结果华支睾吸虫感染后第5~15日,即见肝内少数胆管壁增厚,继而肝内胆管广泛轻度扩张,实验犬肝内病变程度同感染虫体数量及感染时间长短有明显的相关性;本组实验犬B超、CT检查所见肝内胆管阻塞扩张,病变分布特点以及胆管树比例失调与大体解剖所见一致的。结论超声所见同病原学检查具有同等重要的诊断价值,在华支睾吸虫感染初期B超、CT检查所见改变具有早期诊断价值。     

Sonographic findings of active Clonorchis sinensis infection

PURPOSE: The aim of this study was to document the characteristic sonographic findings of clonorchiasis for the diagnosis of active infection in an endemic area. METHODS: In a village in northeastern China, residents underwent fecal examinations for detection of Clonorchis sinensis eggs. Shortly thereafter, residents were examined with abdominal sonography. An experienced radiologist performed the sonographic examinations and analyzed the findings. Subjects whose fecal examinations were positive for eggs were considered to have active clonorchiasis; those whose examinations were negative for eggs were used as control subjects. The distinguishing sonographic features of active clonorchiasis were identified by stepwise logistic regression analysis. RESULTS: The study population comprised 457 subjects; fecal examinations revealed C. sinensis eggs in 316 and no eggs in 141. Four sonographic findings distinguished subjects with active clonorchiasis from control subjects: increased periductal echogenicity (p < 0.001; R = 0.11; sensitivity, 35%; specificity, 91%), floating echogenic foci in the gallbladder (p < 0.001; R = 0.09; sensitivity, 28%; specificity, 94%), diffuse dilatation of the intrahepatic bile ducts (p < 0.01; R = 0.03; sensitivity, 67%; specificity, 48%), and gallbladder distention (p < 0.05; R = 0.02; sensitivity, 3%; specificity, 100%), in decreasing order of significance. Among these 4 sonographic findings, increased periductal echogenicity and floating echogenic foci in the gallbladder were more significantly associated with active infection than were the other 2. CONCLUSIONS: Increased periductal echogenicity and floating echogenic foci in the gallbladder were identified as the 2 most significant findings for the sonographic diagnosis of active C. sinensis infection.
