abstract: OBJECTIVE
  We discuss five scenarios in which retroperitoneal abnormalities are imaged.
  
  
  CONCLUSIONS
  Retroperitoneal disorders may manifest as a focal or diffuse abnormality and may be benign or malignant. Imaging plays a key role in providing a differential diagnosis in patients with retroperitoneal abnormalities.
