title: [Intradiverticular bladder tumor: C.T. assessment].
abstract: OBJECTIVE
  To review the role of computerized tomography on the diagnosis of intradiverticulum bladder cancer. We present images of various cases and perform a bibliographic review.
  
  
  METHODS
  5 cases of intra-diverticulum bladder cancer were identified after a retrospective review. All cases had pathological confirmation. Radiological findings are reviewed for this technique and compared with those obtained by other diagnostic tests.
  
  
  RESULTS
  CT scan allowed the diagnosis of the disease and its extension. Lateral wall was the most frequent diverticulum location and intra-diverticulum mass was the most frequent clinical presentation. Two patients showed tumor calcification, one in the peripheral area, the other allover the tumor area. Vascular behavior of these tumors is similar to the rest of non intra-diverticulum bladder neoplasms. Two cases showed main lumen involvement as well. All tumors were transitional cell carcinomas.
  
  
  CONCLUSIONS
  CT scan is an efficient diagnostic method for the intra-diverticulum carcinoma as well as for extension determination, and it is essential for surgical planning.
