Potential overstaging of bladder cancer by computerized tomography scanning.
We report 4 cases of bladder cancer that was overstaged by computerized tomography. In 2 patients the scans were performed after cystoscopy and bladder biopsy, and overstaging occurred secondary to artifacts produced at the time of biopsy. In the other 2 patients the scans were done before biopsy. In these patients perivesical and periprostatic infiltration interpreted on computerized tomography scans was not found in the surgical pathological specimens.
