Objective To evaluate the manifestations and diagnostic value of pediatric acute appendicitis with dual-source CT (DSCT). Methods Retrospectively analysis of CT features of 97cases of surgically and pathologically confirmed pediatric acute appendicitis in our hospital were performed. Results Among 97 patients, 7 cases were diagnosed acute simple appendicitis, 20 cases with acute suppurative appendicitis, perforated and gangrenous appendicitis in 58 cases, and appendiceal abscess in 12 cases. According to the location of appendix confirmed by CT, 28 cases of appendicitis could not be clearly manifested, the cohort of the remaining 69 cases were composed of 20 cases (29.0%) with appendix located in pelvic, 15 cases (21.7%) with appendix in front of ileum, 11 cases (15.9%) with appendix behind ileum, 12 cases (17.4%) with appendix behind cecum, 3 cases (4.3%) with appendix below cecum, 1 case (1.5%) with appendix outside of cecum, and 7 cases (10.2%) with appendix located in other positions. CT and three-dimensional reconstruction findings were as followed:swelling enlarged appendix, appendicoliths, periappendiceal fat fuzzy, peritoneal thickening, ileocecal thickening, mesenteric lymphadenopathy, periappendiceal mass, and abdominal or pelvic fluid. The diagnostic rate of acute simple appendicitis with CT was 85.7% (6/7), acute suppurative appendicitis was 80.0% (16/20), perforated and gangrenous appendicitis was 100% (58/58), appendiceal abscess was also 100% (12/12), the overall diagnostic yield was 94.8% (92/97). Conclusion DSCT can well demonstrate the anatomical location of appendix and pathological changes of surrounding tissues, and has higher diagnostic accuracy, provide powerful information for surgeons.
