Abstract

The posterior pararenal space(PPS) is a potential space between the posterior renal fascia and thetransversalis fascia. We reviewed 12 cases of posterior pararenal effusion. The causes of the effusion wereretroperitoneal hemorrhage due to trauma(7 cases) or rupture of renal tumor(1 case), pancreatitis(2 cases),urinoma(1 case) and amebic colitis of the cecum(1 case). The CT findings of the effusion were semilunar fluiddensity in the dependant portion of the PPS(9/12), partial obliteration of the PPS extending to the flankstripe(2012), and total obliteration of the PPS extending to the anterior abdominal wall(1/12). The effusion inthe ipsilateral perirenal space and thickening of the ipsilaateral posterior renal fascia were combined in allcases. The effusion in the ipsilateral anterior pararenal space was associated in 11 cases of 12. The effusion inthe PPS is not uncommon findings of retroperitoneal hemorrhage or effusion, but usually related with perirenal oranterior parerenal effusion with no clinical significance.
