A 43-year-old patient with PJS and intestinal polyposis presented to the ER with abdominal pain. Axial contrast enhanced CT images of the abdomen (Panels A–C) demonstrate jejuno-jejunal intussusception, with telescoping of the mesenteric fat and loops of proximal jejunum (intussusceptum, white arrows) into the more distal jejunum (intussuscipiens, black arrow). An intestinal polyp was found to be the lead point and cause of intussusception (clear arrow).
