Abstract

The retroperitoneal space is that indefinite area in the lumber and iliac region which lies between the peritoneum and the posterior wall of the abdominal cavity. The term retroperitoneal cyst or tumor is usually confined by the pathologist to these arising from the structures situated in the retroperitoneal space. Retroperitoneal cysts are that of non-neoplastic nature and originated from retroperitoneal tumor Because the retroperitoneal space is rather extensive and adjacent organs are easily displaced, many of the cysts grow to a large size before giving any clinical manifestation. Frequently, when the patient is first seen, there is an indefinite abdominal mass the exact nature of which is obscure, and the diagnosis is not made until the time of surgical investigation.
