Methods：randomly selected hospital in February 2013 --2015 between December clinically confirmed 26 cases of acute appendicitis surgery patients ultrasound deposit FIG analyzed retrospectively. Results：Acute simple appendicitis in 17 cases，accounting for 65.38%，expressed as sausage-like echo-free zone may be associated with fecal impaction，a cross-sectional showing total eclipse sign，and the root of the appendix visible dot short strip flow signals；acute suppurative appendicitis in 3 cases，accounting for 11.54 percent，showed significantly enlarged appendix，wall rough，uneven thickness，cross-section visible target ring sign，which can be seen around the irregular liquid dark area；gangrenous and perforated appendicitis in two cases，accounting for 7.69%，the performance of the normal appendix tubular structure disappeared，see Fuzzy hypoechoic dark area around it. When a perforated appendix，the appendix wall discontinuity，appendix cavity and appendix visible echogenic gas anechoic chamber to communicate with the surrounding anechoic；appendiceal abscess in 4 cases，accounting for 15.38%.
