Abstract:
We present a case of urinary tuberculosis investigated initially by ultrasound and multidetector computed tomography (MDCT). The MDCT-derived volumetric data were used to generate virtual cystoscopy (VC) images, which revealed a bladder ulcer. The presence of this ulcer was confirmed by conventional cystoscopy-guided biopsy and there was good agreement regarding various features of the ulcer, such as the site, size and shape, as detected by virtual and conventional cystoscopies. VC, a result of simple postprocessing of preacquired MDCT data, proved valuable in the characterization of the bladder lesion in conjunction with CT and ultrasound images. Although a larger study is warranted, in our case these en face VC representations of the ulcer served as useful precursors to conventional cystoscopic biopsy.
