Objective To discuss the spiral CT features of adult intussusception, and to improve the level of the diagnosis.Materials and Methods CT features and the types of 20 cases with adults intussusception, were reviewed retrospectively.Results The types of intussusception were as follows:small intestine-small intestine 10 cases, intestinum ileum-intestinum ileum ascending colon 2 cases, intestinum ileum ascending colon 3 cases, intestinum ileum ascending colon 1 case, colon colon 4 cases. Masses were found at the head part of intussusception in 20 cases, including layering target masses 9 cases, kidney shape masses 10 cases, anomaly masses 6 cases,“Comet tail” signs 8 cases, “double intestines” signs 6 cases (30%), other signs in rear part of intussusception 6 cases. The mesentery fat and the blood vessel were found in the intestines 15 cases. Incomplete intestinal obstruction 3 cases, thickness of the bowel wall 7 cases, dilation of proximal intestinal cavity 4 cases, abdominal ascites 1 case. The liver and the pelvis metastasis 1 case respectively.Conclusion The adult intussusception has characteristic CT features, the “double-intestines” signs in the body and rear part is one of the characteristic CT features.
