Epiploic Appendagitis
- Torsion of epiploic appendages results in vascular occlusion, leading to ischemia
- Inflammation of appendages is self limited. Rarely, it may result in adhesion, bowel obstruction, peritonitis, or abscess
- Common in 4th to 5th decades of life
- Acute pain, most in left lower quadrant - easily mistaken for acute diverticulitis
- Anterior to colonic lumen, sigmoid colon > descending colon > cecum
- Oval fatty mass surrounded by inflammation, 1.5cm and 3.5cm size
- Central high-density focus represents venous thrombosis
- Colonic wall thickening rare
