Purpose : We evaluated the abdominal ultrasonographic findings of Salmonellosis. Materials and Methods : This study included 64 patients who were confirmed as salmonellosis by blood culture. We retrospectively analyzed the abdominal ultrasonographic findings with particular attention to enlarged mesenteric lymph nodes(mesenteric lymphadenitis), thickening of bowel wall, especially terminal ileum and cecum(ileocecitis), hepatosplenomegaly, ascites, gallbladder wall thickening, and enlarged lymph nodes in porta hepatis. Results : The 64 cases were observed as mesenteric lymph node enlargement(44 cases), wall thickening of the terminal ileum and cecum(36cases), hepatomegaly and/or splenomegaly(42 cases), minimal ascites(8 cases), gallbladder wall thickening(6cases), and enlarged lymph nodes in porta hepatis(4 cases). No abnormal finding was seen in 10 patients. Conclusion : The mesenteric lymph node enlargement, wall thickening of the terminal ileum and cecum, hepatomegaly and/or splenomegaly, minimal ascites, gallbladder wall thickening, and enlarged lymph nodes in porta hepatis are suggestive findings of salmonellosis on abdominal ultrasonography in patients with fever and acute abdomen.
