CT findings in diverticulitis Diverticula "Fuzzy" or inflamed diverticulum (ill-defined diverticulum in the area of greatest fat stranding; presumably the causative diverticulum) Regional fat stranding disproportionate to the degree of wall thickening Mild wall thickening (<5 mm on average; potentially asymmetric with greater thickening on the side of the causative diverticulum) Fluid at the root of the sigmoid mesocolon

Although the majority of reported cases have involved the small bowel mesentery, sole involvement of the mesocolon
has been well documented in approximately 20% of cases. Other rare intra-abdominal sites that have been involved by sclerosing mesenteritis are the mesoappendix, peripancreatic area, omentum, and pelvis.[3,6] Grossly, the disease may present as a single mass, multiple masses, or as diffuse thickening of the mesentery.
The tumor was found to be adhered to both the mesocolon
and omentum, and blood vessels were observed to be coming from both; angered vessels bled easily.
One of the nine patients' tumours was small bowel location and another one was transverse mesocolon
location; the others were gastric location.
Within 5 to 10 minutes, the blue dye could be visualized within 1 to 4 lymph nodes in the adjacent pericolic fat or mesocolon
. These nodes were uniquely identified with suture tags by the surgeon in the order they were visualized, so that the pathologist could subsequently identify them; they were designated as first, second, third, and/or fourth SLNs.

Within the abdomen, the most common site for a lymphangioma is the mesentery, followed by the omentum, mesocolon
, and retroperitoneum. The symptoms typically produced depend on the site of involvement and include an abdominal mass or an acute abdomen.

The greater omentum is cut; the coils of small intestine, transverse colon and transverse mesocolon
are mobilized towards the upper abdomen to visualize the ileocaecal junction and vermiform appendix.
