Purpose: To evaluate the radiologic findings of alimentary anthrax Materials and Methods: 19 patients with alimentary anthrax , whiçh was caused by ingestion of contami nated beef , were included in this study. The diagnosis was made by demonstration of Bacillus anthracis in smear and culture of the contaminated mea t. We evaluated the clinical manifestations and the findings of tho racic , abdominal radiographs , cervical , abdominal ultrasonograms and abdominal CT scans. Results: Out of the 19 patients with the alimentary infection , 9 had oropharyngeal form , 18 had abdominal form and 8 had combination of oropharyngeal and abdominal form. The patients had general symptoms and signs such as fever , chill , myalgia. Clinical symptoms and signs were sore throat , throat injection , throat ulcer and patch in oropharyngeal form , and nausea , vomiting , abdomi nal pain , diarrhea , and gross GI bleeding in abdominal form. Radiologic findings included enlarged cervical Iymph nodes(36%) in oropharyngeal form , and paralytic ileus(26%), ascites(26%) , hepatomegaly(21 %), enlar ged mesenteric Iymph nodes(26%) , smallbowel wall thickening(5 %) in abdominal form. In two patients , late complications occurred as intestinal obstruction due to ileal stricture with perforation , and inflammatory changes of pelvic cavity due to ileovesical fistula. Conclusion: Radiologic findings of alimentary anthrax are difficult in differentiation from those of other in flammatory bowel disease , but those radiologic findings with clinical manifestations may be helpf비 in diagnosis and evaluation of disease process in patients with alimentary anthrax
