A 69-yr-old woman presented with a bulky hypogastric mass and abdominal pain. Computed tomography scan showed a mass anterosuperior and contiguous to the bladder wall, with a hypodense content, a voluminous bladder stone, and bilateral hydroureteronephrosis. Intraoperatively, the supravesical mass had the appearance of an infected urachal cyst. An unsuspected high-grade noninvasive papillary transitional cell carcinoma (TCC) of the bladder thoroughly surrounding the bladder stone became evident during the cystolithotomy. Postoperative videourodynamic study showed a normal voiding pattern with bilateral grade 4 vesicoureteral reflux. Early cystectomy was performed for uncontrolled recurrent bladder cancer, and the final pathology indicated pT1G3N0 TCC. © 2009 European Association of Urology.
