      Abstract

      The computed tomography appearance of contrast material extravasated in the right perirenal space is presented. The complication occurred during test injection prior to translumbar aortography. The computed tomography findings were those of a right prerenal collection with high attenuation numbers representing contrast extravasation. Concurrent displacement of the second portion of the duodenum and inferior vena cava was present. No other retroperitoneal abnormalities were noted. The importance of computed tomography for early recognition and follow-up are emphasized.
