- Misty mesestery referes to the CT appearance of mesenteric fat infiltrated by inflammatory cells, fluid (edema, lymph, and blood), tumor, and fibrosis.
- Misty mesentery can be segmental or nonsegmental.
- Nonsegmental mesenteric involvement occurs most commonly in patients with inflammatory bowel disease or in patients who have experienced trauma and have mesenteric bowel injury, major bowel injury, or both. In such cases, the primary lesions are often adjacent to the misty mesentery.
- Segmental misty mesentery commonly results from edematous changes secondary to vascular disorder or neoplastic infiltration. The primary pathologic process can also exist at sites distant from the involved mesentery.
 Imaging Findings
