Infarction of
the lesser omentum. The lesion shows mass effect on lesser gastric curvature and is situated between the liver (L) and the stomach (S), an area that corresponds to the lesser omentum.
Infarction of
the lesser omentum. The hyperattenuating lesion on a sagittal view (arrow). Also small amount of free fluid is seen in the Douglas pouch (*).
Infarction of
the lesser omentum. A fatty lesion (arrow) with hyperattenuating streaks is seen between the left hepatic lobe and the lesser gastric curvature.
Infarction of
the lesser omentum. High-resolution probe ultrasound evaluation shows attenuation on the posterior aspect of the lesion (*).
Infarction of
the lesser omentum. No vascular flow is present within the lesion on colour Doppler ultrasound examination.
Infarction of
the lesser omentum. On ultrasound the echogenic aspect of the lesion (arrow) is suggestive of being lipomatous, and it cannot be easily discriminated from the adjacent hyperechoic pancreas (P).
Infarction of
the lesser omentum. Ultrasound evaluation of epigrastic area shows a hyperechoic lesion (arrow) between the left hepatic lobe (L) and the stomach (S). This lesion was painful and noncompressible. P: Pancreas; A: Aorta; IVC: Inferior Vena Cava.

Intraperitoneal focal fat infarction (IFFI) refers to a group of self-limiting abdominal diseases where the primary insult is acute inflammation of intraperitoneal fat. They commonly mimic the more common causes of acute abdomen such as acute diverticulitis and acute appendicitis. The group includes:
- epiploic appendagitis
- omental infarction: can be primary or secondary
- perigastric appendagitis (rare)
They share common risk factors, including obesity, recent abdominal surgery, and trauma.
Differential diagnosis
- acute appendicitis
- acute diverticulitis
- omental caking from peritoneal metastatic disease
- mesenteric panniculitis
- fat-containing tumors
