Info

Partially encapsulated fatty proliferation of the central mesentery with "misty" appearance and several small lymph nodes contained by a fatty "halo" or fat ring sign. No soft tissue nodules.

Case Discussion

Classic imaging findings of mesenteric panniculitis, which is benign and typically does not result in clinical symptoms. This can be differentiated from more concerning mesenteric pathologies such as lymphoma, liposarcoma, or carcinoid tumors based on the characteristic appearance and lack of soft tissue.
