PERITONEAL STENOSIS MIMICKING A RIGHT RETROPERITONEAL MASS

We report a case of an incidentally diagnosed apparently isolated sple nosis nodule located in the hepatorenal peritoneal recess. According t o imaging features, this mass was a non-renal retroperitoneal tumor. I n spite of the isolated location, the history of splenic rupture shoul d have led to a heat-damaged red blood cell scintiscan and would thus have avoided percutaneous biopsy.
