Objective To study CT features and pathological basis of intussusception in adult. Methods Twenty four cases with 28 foci of intussusception were reported. Among them, 21 cases were secondary to primary pathology including lipoma(7),polyp(3),lymphoma(3),adenocarcinoma(2),leiomyoma(2),angioma(1),metastases(1),diverticulum(1),appendicitis(1), and eosinophilic granuloma (1). Results CT detected 22 layering target masses and 15 “Comet tail” signs accompanied by kidney shape masses in all 24 cases with 28 foci, and the diagnostic accuracy by CT was 86%. Of the 21 cases with primary lesions, 19 primary lesions were detected by CT, demonstrating classic features in cases of lipoma. Conclusion There was a high sensitivity of CT to detect the underlying lesions of adult intussusception, and lipoma could often be diagnosed correctly, so CT is the method of choice for diagnosis of adult intussusception.
