Epiploic Appendagitis

General Considerations

  • Uncommon cause of acute abdominal pain
  • Occurs most often in men in 4th and 5th decade
  • Inflammation of epiploic appendages (appendices)
    • Peritoneal outpouchings originating from serosal surface of colon

  • Diagnosis requires cross-sectional imaging
  • Inflammation may be caused by venous occlusion
  • “Secondary” epiploic appendagitis is caused by inflammation of an adjacent structure
