Gastric wall fatty infiltration
Gastric wall fatty infiltration refers to an appearance seen on CT of the abdomen whereby the wall of the stomach is thickened due to infiltration of fat into the submucosa.
Although it can be seen in the context of Crohn disease it is more commonly seen in the asymptomatic general population. It is most prevalent in those of large body habitus especially those with a large quantity of visceral adipose tissue i.e fat in the abdominal cavity between the organs. It also seems to be more common in men older than 45 years 1.
The majority of the patients with gastric wall fatty infiltration also have submucosal fat deposition in the small and large bowel, the so-called fat halo sign.
