Pseudoureterocele: a uroradiologic entity

An analysis of 5 patients with an acquired dilatation of the distal ureter, simulating a simple ureterocele, is herein reported. Radiologically, pseudoureteroceles are more likely to be associated with ipsilateral upper tract obstruction and have asymmetric intravesical dilatation. The urologist should be aware of this urographic deformity, for the majority of pseudoureteroceles are related to malignancy involving or invading the bladder.
