Objective: To analyze CT, ultrasonogr aphy (US) and barium enema (BE) findings of intussusception in adults, and to im prove its diagnostic accuracy. Materials and Methods:Six adult patients with intussuscept ion were collected, including 5 men and 1 wonman, 14~71 years aged (median=52). The diagnosis was confirmed surgically and pathologically in 5 and clinically i n 1. Imaging examinations included double contrast BE (n=4 ), US (n=4) and CT (n=3). Three pati ents underwent more than one method. Results:A localized mass was found in all 6 cases. US find ings included: (1) thin hetero or hypoechoic rim (intussuscipiens), (2) cent rallyhyperechoic mass (intussusceptum, n=3), (3) Hypoech oic or heteroechoic mass (primary tumor) in the distal part of intussusception ( one each, respectively). CT findings included: (1) targetlike heterogeneous so ft tissue fatcontaining mass (n=3), (2) tongueshaped i ntussusceptum (n=2), (3) oral contrast material in intussu scipiens (n=1) or intussusceptum (n= 1). Typical coilspring sign was seen in all 4 patients who underwent BE exam. The intussusceptions were caused by colon carcinoma (n=2) or lymphoma (n=4), and presented as ileocolic (n=5) or colocolic (n=1) type. Conclusion: Besides the classical coil spring sign on BE, targetlike mass with fat component and tongueshaped intussusceptum are the t ypical CT and US findings of intussusception in adults. Cross sectional imaging technique is superior to BE in its providing additional information about viscer al and lymph node metastasis in the patients with primary malignancy.
