Colonic perforation by a transmural and transvalvular migrated retained sponge: Multi-detector computed tomography findings

Figure 3 Multi-detector contrast-enhanced computed tomography. An 80 mm thick maximum intensity projection (MIP) reconstructed image is shown; The laparotomy sponge (arrow-heads) is clearly depicted in the right flank extending from the ileo-cecal valve to the proximal transverse colon where the perforation occurred; Stomach (*) and jejunal loops (°) appear opacified by orally administered iodinated contrast medium (Gastrografin).
