OBJECTIVE.A variety of retroperitoneal diseases such as pancreatitis, infection, and trauma may cause fluid collections in the three major retroperitoneal spaces. The purpose of our study was to elucidate flow patterns of fluid between the various compartments to assist the clinical-radiologic assessment and treatment of various retroperitoneal diseases.MATERIALS AND METHODS. In eight cadavers, CT guidance was used to selectively inject 35-1000

Intercommunication of the various extraperitoneal compartments occurs predominantly via the fascial-defined spaces, which contain mainly adipose tissue, but potential conduits exist through the communicating neurovascular structures where the fascia is anatomically perforated.
