Presentation
Recurrent urinary tract infections.
Patient Data



Plain radiograph shows no calcification along the urinary tract. Post intravenous contrast radiograph shows dilatation of the left distal ureter showing a "cobra's head'' appearance and "radiolucent halo" effect. Findings represent intravesical ureterocele of left ureter.
Case Discussion
Ureterocele represents abnormal dilatation of the distal ureteric segment. Ureteroceles may be associated with either a single or a duplex ureter. Ureteric duplication is present in about 75% of cases of ureteroceles. Ureteroceles have a female predilection.
Ureteroceles can be further classified into simple and ectopic types.
