| Answer | Epiploic appendagitis |
| Comments | Epiploic appendagitis is a benign and self-limiting inflammatory condition involving an epiploic appendage. On ultrasound, it typically presents as a noncompressible, oval-shaped hyperechoic mass adjacent to the colon, often surrounded by a hypoechoic rim that reflects inflammation of the visceral peritoneum. Color Doppler imaging usually demonstrates absent or minimal internal vascularity within the lesion. The adjacent bowel wall is generally normal or only mildly reactive, which helps differentiate epiploic appendagitis from acute appendicitis or diverticulitis. Laboratory inflammatory markers are often normal or only mildly elevated. Accurate recognition of these characteristic ultrasound findings can obviate unnecessary surgical intervention, as conservative management is usually sufficient. Awareness of this entity is particularly important in the evaluation of patients presenting with acute abdominal pain. |
