Axial CT image of the pelvis showing multiple sigmoid colonic diverticula (orange arrow). Many of these diverticula demonstrate markedly hyperattenuating material filling them (orange arrowheads) which was proven to be barium sulfate after resection of the colon. There is a sigmoid anastomotic donut in trans-axial section (blue arrow) with hyperattenuating material within it as well. Evidence of classic gross barium material along the peritoneal surfaces was not seen in this case
