Answer- D Both B and C
Goblet sign & Stipple sign describe the appearance of ureteral dilation below the site of an intraluminal ureteral filling defect, best seen at retrograde pyelography (RGP).
The Stipple sign refers to the pointillistic end-on appearance on IVP or RGP of contrast material tracking into the interstices of a papillary lesion.
Stipple sign is best seen in large papillary bladder tumors.
CT urography is IOC for evaluation of the upper urinary tract.
Ureteral tumors are often characterized by ureteral dilation below the site of the lesion, creating the appearance of a “goblet” (better appreciated on RGP)
