Last revised by Dr Daniel J Bell on 09 Jan 2022

Misty mesentery sign is a sign on CT in which mesenteric fat with increased attenuation mimics mistiness. Just as with fat stranding elsewhere, a number of processes can lead to the appearance including infiltration by inflammatory cells, edema, lymphatic accumulation, hemorrhage, tumor infiltration, and fibrosis.
