I would recommend that you discuss this with your doctor
. A gastroenterologist
or stomach specialist may also be helpful in diagnosing your condition. As this is a relatively complex and rare condition, discussing at length the condition with someone who is more familiar with the actual details is essential.
The omentum is the fat that surrounds the intestines in the stomach. It is external to the intestines. It blends together and forms a pad. In obese patients, this become full of fat. As with any tissue, it survives by getting blood through blood vessels.
An infarction is a terms that describes tissue death caused by decreased blood supply. An omental infarction refers to decreased blood supply to the omentum that subsequently causes death of the tissue.
This is a relatively rare condition, and when it occurs it is mostly in children. It is quite difficult to determine exactly if this is the case, as often inflammation can look similar (as if the appendix nearby is inflamed). The most definitive way to determine what is occurring is to biopsy the lesion -- that is to do surgery
and actually see what the area looks like. This however is invasive and therefore not ideal.
Talk to your doctor. This is a rare condition that requires some careful attention. Good luck!
