Adult intussusception: A retrospective review of 41 cases

Figure 3 Efferent loop intussusception with a tube. A 70-year-old woman underwent Billroth II gastrectomy and efferent loop intubation for enteral nutrition. One month postoperatively, CT at the level of the lower abdomen shows a round, target-shaped mass in the left abdomen. The mass consists of a hyperdense tube (arrow), a “half-moon” shaped hypodense area medial to it, the intussuscepted mesenteric fat and a soft tissue rim representing the opposing walls of the intussuscipiens and the intussusceptum.
