    Abstract:
    A 54-year-old male with the chief complaint of bilateral flank pain was admitted to our hospital. Blood chemistry test revealed marked azotemia and retrograde pyelogram showed bilateral hydronephrosis with median shift of narrowed ureters. Abdominal CT scan demonstrated a well-defined dense mass around the aorta implicating bilateral ureters. These findings were interpreted as aortic perianeurysmal fibrosis resulting in bilateral ureteral obstruction. On laparotomy, a large hard mass was found in the lower part of aorta, vena cava, common iliac vessels, inferior mesenteric artery and bilateral ureters. Because of the extension of the mass, ureterolysis and intraperitoneal displacement of ureters wrapped with isolated omentum was performed. Postoperative recovery from azotemia and ureteral obstruction was satisfactory. Biopsy specimen of the mass showed marked fibrosis with non-specific inflammation.
