Abstract:
PurposeAdult intussusception is rare, and clinical symptoms are atypical and tend to be misdiagnosed. This study aims to explore the imaging features of intussusception on multi-slice CT (MSCT) and to improve the diagnosis of this disease. Materials and Methods Sixty cases with intussusception conifrmed by pathology were recruited and imaging ifndings including sleeve head lesions, set sheath canal, exhumation of intestine, involved mesenteric fat, and blood vessels were retrospectively analyzed. Results The direct sings included 60 cases with target signs, 44 of them with single target signs and 16 of them with double target signs; the shape was kidney like in 39 cases and irregular in 21 cases; 22 cases showed double intestinal signs, 15 cases showed comet tail signs, and 25 cases showed mountain like with different direction. The indirect signs included 60 cases with thickened intestinal wall and 45 cases with mesenterium fat and vessel in enteric cavity, 12 cases with adjacent mesenteric mass and enlarged retroperitoneal lymph nodes, 15 cases with ascites, 7 cases with metastatic tumors, including 4 cases of liver metastasis, 2 of pelvic ossiifcation metastasis, and 1 of multiple organ metastasis, 1 case combined with renal calculus and 3 case with ureteral caluli. Conclusion There are some special CT manifestations of adult intussusception. Mountain like sign with different direction at the tail is one of the characteristics. CT plays an important role in clinical procedure.
