Ureteral pseudodiverticulosis: a unique case diagnosed by multidetector computed tomography

Area of Science:

• Urology
• Radiology
• Medical Imaging

Background:

• Ureteral pseudodiverticulosis is a rare condition characterized by multiple outpouchings of the ureteral wall.
• Diagnosis often relies on advanced imaging techniques.
• Differential diagnosis includes other ureteral pathologies.

Observation:

• A case of ureteral pseudodiverticulosis was diagnosed using multidetector computed tomography (CT).
• Axial and coronal reformatted CT images demonstrated multiple small (2-4 mm) outpouchings in both ureters.
• Unenhanced CT also identified a 6-mm left ureterovesical junction stone and a suspicious high-attenuation lesion in the right ureterovesical junction.

Findings:

• Multidetector CT effectively visualized the characteristic ureteral pseudodiverticulosis.
• The imaging incidentally detected a ureteral stone and a potential uroepithelial neoplasm.
• The findings underscore the utility of CT in diagnosing ureteral abnormalities.

Implications:

• This case emphasizes the importance of multidetector CT in diagnosing ureteral pseudodiverticulosis.
• The incidental findings highlight the potential for CT to detect co-existing ureteral pathologies like stones and neoplasms.
• Accurate diagnosis through CT imaging is crucial for appropriate patient management and treatment planning.
