Ureteral pseudodiverticulosis: a unique case diagnosed by multidetector computed tomography.

Presented is a case of ureteral pseudodiverticulosis diagnosed by multidetector computed tomography (CT). Axial and coronal reformatted CT images revealed multiple small (2-4 mm) outpouchings of both ureters, characteristic of ureteral pseudodiverticulosis. The unenhanced CT also revealed a 6-mm stone at the left ureterovesical junction and a high attenuation lesion at the right ureterovesical junction suspect for an associated uroepithelial neoplasm.
