Diagnosing Omental Infarction

Omental infarction classically presents on CT as an ill-defined area of fat stranding that evolves into a focal, heterogeneous mass located between the anterior abdominal wall and the colon.

The crucial differentiating feature from adjacent inflammatory pathologies is disproportionate fat stranding without bowel wall thickening.

On sonography, it appears as a fixed, echogenic, non-compressible, and tender mass with reduced or absent color flow.
