Ureteral pseudodiverticulosis is a relatively rare condition and has been diagnosed by retrograde urography and excretory urography. Ureteral pseudodiverticulosis is also suspected to be a potential risk factor for the development of urothelial carcinoma. We report the case of a male in his 70 s who was suspected to have right ureteral pseudodiverticulosis accompanied by multifocal urothelial carcinoma based on CT urography findings. After surgery, the pathological findings confirmed the presence of ureteral pseudodiverticulosis and multifocal urothelial carcinoma in his right ureter and bladder. To the best our knowledge, this is the first reported case of ureteral pseudodiverticulosis with concurrent urothelial carcinoma detected by CT urography. Since CT urography has replaced excretory urography as the first-line imaging test for investigating patients with high risk for upper tract urothelial carcinoma, it is important to recognize the characteristic findings of ureteral pseudodiverticulosis on CT urography.
输尿管假性憩室病是一种相对罕见的疾病，已通过逆行尿路造影和排泄性尿路造影得以诊断。输尿管假性憩室病也被怀疑是尿路上皮癌发生的一个潜在危险因素。我们报告了一例70多岁男性患者的病例，基于CT尿路造影结果，怀疑其患有右输尿管假性憩室病并伴有多灶性尿路上皮癌。手术后，病理结果证实其右输尿管和膀胱存在输尿管假性憩室病和多灶性尿路上皮癌。据我们所知，这是首例通过CT尿路造影检测到的并发尿路上皮癌的输尿管假性憩室病病例。由于CT尿路造影已取代排泄性尿路造影，成为对上尿路尿路上皮癌高危患者进行检查的一线影像学检查，因此认识CT尿路造影上输尿管假性憩室病的特征性表现很重要。
