Manifestations and Diagnostic Value of CT in Acute Appendiatis in Children

Objective:To study the manifestations and diagnostic value of CT in acute appendicitis in children.Methods:Retrospective analysis was made of the clinical and CT data of 55 cases of surgically and pathologically confirmed acute appendicitis in children from January 2007 to December 2008,summing up their CT features and clinical value.Results:In the 55 cases of acute appendicitis,12 cases were of catarrhal type,25 cases of suppurative type and 18 cases of gangrene type.CT manifestations were as follows: swelling enlarged appendix (37/55);appendiceal intraluminal fecalith (35/55);appendiceal intraluminal gas (17/55);appendiceal perforation and abscess formation (18/55);inhomogeneous in creased density of periappendiceal tissue (19/55);adjacent cecal wall thickening (24/55);ascites (11/55);ileus (5/55);and its complications such as liver abscess and NEC.Conclusion:CT manifestations of acute appendicitis in children have their own characteristics.CT examination can show the pathological changes of appendix and surrounding tissues,providing an objective basis for clinical diagnosis.
