Abstract:
Objective To investigate the CT manifestations of Meckel's diverticulum and its complications in children. Methods Retrospective analysis of Clinical and CT findings in 25 cases with pathologically proved Meckel's diverticulum. The unenhanced and contrast-enhanced CT were obtained in all patients. Results (1)The direct signs: the diverticulum cannot be shown in 5 cases; the diverticulums were found around the navel or in lower right abdomen in 20 cases. The blind-ending fluid-filled or gas-filled structures were found in 9 cases, with heterogeneous ring-enhancement. The tubercle-like structures were detected in 11 cases, which showed no enhancement in 4 cases, and homogeneous enhancement in 3 cases,and heterogeneous enhancement in 4 cases. (2) The indirect signs included intestine obstruction in 8 cases,swelling fat layer surrounding the diverticulum in 9 cases, free gas around the diverticulum in 3 cases,thickened mesentery in 8 cases, ascites in 4 cases, and intussusception due to inverted Meckel's diverticulum with "target sign" in 1 case. (3) CT classification: with diverticulitis or diverticular bleeding in 20 eases; with intestine obstruction or intussusception in 8 cases; bands-caused obstruction in 7 cases;intussusception in 1 case; with perforation in 3 cases. Conclusion Meckel's diverticulum and its complications have typical CT findings, and CT can clearly demonstrate diverticulum's shape, margin,internal components and surroundiug tissues.
