Marked increased wall thickness with a large exophytic mass is seen at the distal of descending colon and proximal sigmoid, accompanied by severe pericolic fat stranding and desmoplastic reaction. Several extraluminal air bubbles and a 20 mm walled-off paracolic fluid collection are also evident, suggesting tumour site perforation.
Segmental wall thickening is also evident at the adjacent small bowel loops inferring tumoral invasion.
In addition, several regional and para-aortic enlarged lymph nodes are seen with SAD less than 11 mm.
