A transrectal ultrasonography was performed, showing a large left retrovesical hypoechoic mass with a posterior enhancement and impure content, compressing the urinary bladder and protruding into the bladder lumen (Figure 1).

A pelvic MRI was performed to identify precisely the origin of the cystic mass using a T1-weighted, T1-weighted with gadolinium injection, and T2-weighted sequences in the axial and coronal plans (Figures 3 and 4).

A pelvic MRI was performed to identify precisely the origin of the cystic mass using a T1-weighted, T1-weighted with gadolinium injection, and T2-weighted sequences in the axial and coronal plans (Figures 3 and 4). From its posterolateral side emerges a tubular structure crossing the iliac vessels anteriorly, which was considered an ectopic ureter (Figures 4 and 5).
