Katryana Mary Hanley-Knutson MD, Presenter: Nothing to Disclose

1.Review the normal retroperitoneal anatomy and radiologic signs to localize pathology to the anterior and posterior pararenal spaces 2. Illustrate the common pathology and  ways of disease spread in the anterior and posterior pararenal spaces with a series of cases

 We present, describe and analyze CT anatomy and pathology of the the anterior and posterior pararenal spaces with Multidetector CT and multiplanar reformations.  Cases will include, but not limited to pancreatitis , diverticulitis, retroperitoneal gas dissevting through facial plances, malgnancies including primary and neoplastic disease.  Detailed description and demonstration of disease and it's spread will be demonstrated to include: Anterior pararenal space spread to lateral edge of the quadratus lumborum muscle Retromesenteric plane role in spread of disease accross midline Gerota (Retromesenteric)  and Zuckerkandl(retrorenal) facial plance fusion  Subperitoneal spread from retroperitoneum along the peritoneal ligaments  Interfacial spread alonf the retromesenteric, retrorenal, and interfascial planes to bare area of liver, liver hilum and left diaphragm
