The fat ring sign (also known as a fat halo sign) describes preservation of fat around the mesenteric vessels and around soft tissue nodules on the background of diffuse fat stranding in patients with mesenteric panniculitis or mesenteric lipomas.
This finding may help distinguish mesenteric panniculitis (fat ring sign present) from other mesenteric processes such as lymphoma, carcinoid tumor, or carcinomatosis (fat ring sign absent).
