Neoplasms originating in bladder diverticula are characterized by early transmural invasion and a tendency for higher histopathological grades, which make prompt diagnosis and treatment crucial in these tumors. Filling defects caused by intradiverticular tumors cannot always be visualized in intravenous urography and/or cystography. Cross-sectional imaging methods including ultrasonography, computed tomography and magnetic resonance imaging have been used singly or in combination in neoplasms of the lower urinary tract. We herein present radiological findings in four patients with intradiverticular bladder neoplasms. Although diverticula were readily visualized in all patients, intravenous urography did not detect the neoplasm in two patients. Accurate diagnosis and staging were possible in all patients with both ultrasonography and computed tomography. In one patient magnetic resonance imaging clearly showed the intradiverticular tumor and peridiverticular extension. Cross-sectional imaging methods should be used in the evaluation of bladder diverticula as an adjunct to intravenous urography.
起源于膀胱憩室的肿瘤具有早期透壁浸润和组织病理学分级较高的倾向，这使得对这些肿瘤进行及时诊断和治疗至关重要。静脉肾盂造影和/或膀胱造影不一定能显示憩室内肿瘤所致的充盈缺损。包括超声、计算机断层扫描和磁共振成像在内的横断面成像方法已单独或联合用于下尿路肿瘤。我们在此呈现4例膀胱憩室内肿瘤患者的影像学表现。尽管所有患者的憩室均易于显示，但静脉肾盂造影未检测出2例患者的肿瘤。超声和计算机断层扫描对所有患者均能进行准确诊断和分期。1例患者的磁共振成像清晰显示了憩室内肿瘤及憩室周围浸润。横断面成像方法应用于膀胱憩室的评估，作为静脉肾盂造影的辅助手段。
