Entero-enteric intussusception in a 65-year-old male presented with acute abdominal pain and vomiting. Axial CT image (a) and coronal CT image (b) showing invagination of distal jejunal bowel loops (the intussuceptum) (yellow arrowheads) into proximal ileal bowel loops (the intussuscipient) (red arrowheads) with subsequent dilated proximal small bowel loops (stars). c Axial CT image showing the lead point for this intussusception; intra-mural soft tissue mass lesion (circle). Sausage shape appearance is seen in axial CT images (a & c). d Axial CT image at another level showing the typical target sign (curved arrow)
