Abstract:
We report a case of benign colonic tubular adenoma arising in a 36-year-old female at the site of ureterosigmoidostomy performed 25 years before. The tumor was revealed by recurrent episodes of pyelonephritis; hydronephrosis was present. On colonic enema, the tumor appeared lobulated, 4 cm in diameter. CT scan showed a multiloculated mass, which enhanced after injection. Pathology revealed a tubular adenoma of the colon with cystic dilatation of glandular structures. The role of imaging studies in the follow-up of patients after ureterosigmoidostomy is discussed.
