title: [Calcified bladder squamous carcinoma: radiologic considerations].
abstract: OBJECTIVE
  To report a case of squamous cell carcinoma of the bladder, an uncommon tumor type, that presented with wide calcified areas. The literature on calcified bladder tumors is reviewed with special reference to the diagnostic aspects.
  
  
  RESULTS
  The plain film, US and CT findings are presented. All the diagnostic imaging techniques demonstrated calcifications on the tumor surface and the characteristic curvilinear shape of this lesion.
  
  
  CONCLUSIONS
  Calcified bladder carcinoma is rare and occurs in only 0.5% of the cases evaluated by conventional radiology. All calcifications probably arising in the bladder detected on conventional radiological evaluation should be studied further with other imaging techniques. If its etiology is unclear, cystoscopy with biopsy and/or a microbiological study should be performed.
