Abstract

A transurethral resection of bladder tumor (TURBT) is the primary treatment modality for bladder cancer. The common complications of TURBT include urinary tract infections, a hemorrhage requiring transfusion, and bladder perforation. Extravesical metastasis and intraperitoneal seeding of tumor cells following TURBT are very rarely reported. This report reviews a case of extravesical metastasis occurring after a repeated TURBT of non-invasive bladder cancer.

  Fig. 1. Initial contrast-enhanced CT image in a 70-year-old man. A. A contrast-enhanced CT image on early nephrographic phase shows an about 2.0 cm sized homogenous enhancing mass at right posterolateral wall of bladder (arrow). B. A contrast-enhanced CT scan on excretory phase performed 8 years after first visit. An about 2.7 cm sized polypoid mass (arrow) is located in the lower anterior wall of bladder with no perivesical fatty infiltration nor abnormal lymphadenopathy. C. Follow-up contrast-enhanced CT image on excretory phase, approximately four months after the final transurethral resection of bladder tumor. Ill-defined enhancing masses are developed in the perivesical space (arrows). This mass seemed to have invaded the bladder, seminal vesicle and adjacent peritoneum. D. A coronal reconstructed CT image shows ill-defined, enhancing soft tissue lesion along the adjacent peritoneum (arrows). E. Low power photomicrograph of the pathologic specimen obtained at extra-vesical mass around the bladder. Low power photomicrograph of the pathologic specimen obtained at extra-vesical mass around the bladder (arrow) shows low-grade infiltrating urothelial carcinoma (original magnification, × 200; hematoxylin-eosin stain).
