Introduction: Adult intussusception is an infrequent cause of intestinal obstruction and differs from childhood intussusception in its presentation, etiology, and treatment. Almost 90% of adult intussusceptions are secondary to a pathological condition that serves as a lead point and most of them require surgical intervention. Method: Computed tomography (CT) is the most sensitive diagnostic modality which distinguishes intussusceptions with and without a lead point. This paper presents the clinical presentation and etiopathogenesis of adult intussusception as demonstrated by CT. Observation and results: Five cases of adult intussusception were evaluated and the various etiologies included an intestinal polyp, bowel wall leiomyoma, jejunal lipoma, calcified lymph and idiopathic causes. Conclusion: Adult intussusception is a rare but challenging condition for the surgeon. Diagnosis is usually missed because of nonspecific and subacute symptoms. With the advent of MDCT in imaging of acute abdominal emergency, the detection of intussusception has increased.
