title: Campylobacter ileocolitis mimicking acute appendicitis: differentiation with graded-compression US.
abstract: In nine patients with clinical symptoms of acute appendicitis, graded-compression ultrasound (US) did not depict the appendix but instead demonstrated mural thickening of the terminal ileum and part of the colon, as well as moderately enlarged mesenteric lymph nodes. In one patient a normal appendix was removed; eight patients recovered without treatment. Infection with Campylobacter jejuni was proved in all nine patients. In four patients, an unnecessary appendectomy was avoided because of the US findings. Graded-compression US enables differentiation between acute appendicitis and Campylobacter ileocolitis, a vital differentiation, since surgery is almost certainly not indicated for the latter.
