Goblet sign (ureter)

The goblet sign, also known as the champagne glass sign, refers to the appearance of the ureter when it is focally dilated by an intraluminal mass. It is best seen when the ureter is opacified by retrograde contrast (retrograde ureterogram). Presence of this sign indicates the pathology to be chronic, permitting the lesion to be accommodated in the ureter.

Although most frequently caused by transitional cell carcinoma, a number of other entities can lead to the same appearance :

• transitional cell carcinoma of the ureter: most common
• metastatic disease into the ureter
• endometriosis involving the ureter
