Pseudoureterocoeles are acquired dilatations of the submucosal portion of the distal ureter that mimic simple ureteroceles. The appearance of the radiolucent wall surrounding the dilated distal ureteral segment (cobra head sign) is an important differentiating point.

The distinction is important, since most pseudoureterocoeles were related to malignancy involving the bladder.

In a pseudoureterocoele:

the lucency or halo is thicker than that of a uterocele and is poorly deﬁned; in cases of tumours, it may be irregular and may show a ﬁlling defect within the ureterocele
there is asymmetry of the dilated ureteral lumen
there is moderate to severe obstruction of the upper tract
there is evidence of an acquired cause, such as a calculus or abnormal vesical mucosal pattern
rarely, thickening of this lucency in a patient with a known ureterocele is usually associated with a complicating process, such as oedema with a calculus
