Retroperitoneal masses: Introduction. Retroperitoneal masses: Retroperitoneal masses is a condition in which there are growths or tumors that develop behind the peritoneum, a membrane that covers most of the abdominal organs.
A retroperitoneal hematoma is a pocket of blood found in the lower back in an area known as the retroperitoneal space.reating a retroperitoneal hematoma through surgery involves evacuating the collected blood and stopping the cause of bleeding. Retroperitoneal hematomas may grow significantly enough to reduce blood flow to the rest of the body, because the blood is collecting in the peritoneal space.
