diffuse mesenteriale Flüssigkeitseinlagerungen (misty mesentery sign)

Misty mesentery is a term used to describe the CT appearance of mesenteric fat with increased attenuation. 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.

Associations

  • infiltration of lymphatics by gastrointestinal adenocarcinoma
• idiopathic
• cirrhosis: due to edema secondary to portal hypertension
• adjacent inflammation
  • appendicitis
  • inflammatory bowel disease: typically Crohn disease
