The omentum is a fold of the peritoneum, the lining of the abdominal cavity. It hangs down from the stomach and the proximal part of the small intestine. The omentum is divided into two main parts:
- Greater Omentum: Located on the front and side of the abdominal organs.
- Lesser Omentum: Connects the stomach to the liver.
The posterior lateral omentum refers to the back and side regions of the omentum. It plays a role in fat storage, immune responses, and infection containment within the abdomen.
Types of Posterior Lateral Omentum Masses
Posterior lateral omentum masses can vary based on their nature and origin. Common types include:
- Benign Tumors:
- Lipomas (fat tissue)
- Hemangiomas (blood vessel growths)

- Malignant Tumors:
- Omental carcinomatosis (cancer spread to the omentum)
- Sarcomas (cancer of connective tissues)
- Cysts:
- Omental cysts (fluid-filled sacs)
- Infectious Masses:
- Abscesses (collections of pus)
