Fig. 1A —76-year-old man with transitional cell carcinoma of urinary
bladder and normal findings at initial cystoscopic examination. Transverse
(A) and virtual cystoscopic (B) images show sessile mass
(arrow) measuring 6 x 12 mm on left anterolateral wall of
urinary bladder. Patient underwent second cystoscopic examination, at which CT
findings were confirmed.

Fig. 2A —74-year-old man with small cell carcinoma of urinary bladder
with perivesical extension. Transverse (A) and virtual cystoscopic
(B) images show large mass on posterior wall of urinary bladder. Tumor
extends into perivesical fat (arrow, A).

Fig. 3A —42-year-old man with apparent mass of urinary bladder wall
that proved to be inflammation at histologic examination. Transverse
(A) and virtual cystoscopic (B) images show large mass on right
wall of urinary bladder. Transverse tomographic images show irregularity of
perivesical fat, which suggests extravesical extension. Findings at histologic
examination were negative for malignancy.

Fig. 4C —53-year-old woman with multiple transitional cell carcinomas
of urinary bladder. Virtual image depicts two other lesions involving left
posterolateral wall of urinary bladder: sessile mass (short arrow)
measuring 5 x 7 mm and polypoid tumor (long arrow) smaller than
5 mm that was appreciated only on virtual images. CT findings were confirmed
at conventional cystoscopy.

Fig. 5C —54-year-old man with transitional cell carcinoma of urinary
bladder. Virtual image shows small polypoid lesion (arrow) involving
left lateral wall. Lesion was not confirmed on conventional cystoscopy and was
attributed to presence of blood clot.

Fig. 6A —68-year-old man with transitional cell carcinoma of urinary
bladder with perivesical extension. Transverse (A) and virtual
cystoscopic (B) images show large tumor of left posterolateral wall of
urinary bladder. Mass has irregular surface and extends into perivesical fat
(white arrow, A), which is appreciated in A. Urinary
bladder calculi (black arrow, A) also are present.

Fig. 7 —73-year-old man with transitional cell carcinoma of urinary
bladder infiltrating distal part of right ureter. Coronal reformatted image
shows mass on right posterolateral wall of bladder infiltrating right
ureterovesical junction, extending in distal part of ureter (arrow),
and causing ureteral dilatation.
