CT of calcified bladder masses

Calcifications observed in bladder lesions are seen on plain films with an incidence of 0.5-7.0%. Four cases of calcification were noted on CT in 38 consecutive bladder scans (10.5%). Calcifications were noted both on the surface, and within the lesions. One of the cases with malakoplakia had calcification. This has not been reported to date. With CT, it is expected that calcification in bladder lesions will be found with increasing incidence, and should be looked for.
