title: Bowel intussusceptions in adults: the role of imaging.
abstract: Intestinal intussusception in adults is a rare condition, accounting for about 0.003-0.02% of all hospital admissions. This condition in adults represents only 5% of all cases of intussusceptions and is different from paediatric intussusception, which is usually idiopathic. In contrast, almost 90% of cases in adults are secondary to various pathologies that serve as a lead point, such as polyps, Meckel's diverticulum, colonic diverticulum, or malignant or benign neoplasm. The aim of the present study was to assess the capabilities of multislice computed tomography (MSCT) in the diagnosis and correct characterisation of intussusception, especially in distinguishing between intussusceptions with a lead point and those without. Indeed, although the MSCT findings that help to differentiate between lead point and non-lead point intussusceptions have not been well studied, abdominal MSCT remains the most sensitive radiological tool to confirm bowel intussusceptions. Moreover, differentiating intussusceptions with a lead point condition from those without is crucial for directing the patient towards the most appropriate treatment, avoiding surgery when not necessary.
