[Cross-sectional imaging findings in intradiverticular bladder tumors: Case report].
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.
