‘Mass’ containing intussusception; umbilical region. The photograph shows the intussusception encountered upon opening the anterior abdominal wall, just deep to the umbilical region, through a midline incision. This had been palpated as an abdominal mass during the patient’s examination. Virtually the whole colon is invaginated and ‘crammed’ within this mass of gut, occupying a relatively small volume of space.
