ABSTRACT
Abdominal CT scans in 11 adult in tussusceptions were analyzed. Patients were 8 males and 3 females. Their ages ranged from 18-53 years [mean age: 31.5 years]. All were clinically unsuspected and all were confirmed at surgery. In 9 of our 11 patients, there was organic lesion [benign or malignant tumor] while in 2 patients no cause was found at surgery and thus they were considered idiopathic. The surgical management in our cases involved 7 cases of right hemicolectomy, 2 cases of resection anastomosis and 2 cases of reduction and fixation. One of our cases was jejunoileal intussusception, two were ileoileal, 4 were ileocolic and 3 were colocolic. The last of our cases had synchronous multiple jejunojejunal and colocolic] intussusceptions. We reviewed the different reports about the CT findings in adult intussusception in order to put a spotlight on every sign of the disease and to define its significance. We found "target" mass in 5 cases, one of which showed intramural air crescent. "Layering" pattern was found in 3 cases. "Reniform" mass was seen in 2 cases and the last case showed a sausage shaped" mass. Five of our cases felt in stage [1] and 6 were of stage [2]. Our results suggest that the internal anatomical detail of the mass is more important in its staging than its overall shape. We concluded that not only is CT valuable in the diagnosis of adult intussusception but it is also more informative than other techniques. It can detect the early changes of vascular compromise which influences the surgical plan. Moreover, it can occasionally suggest the underlying organic cause of the disease
