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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
