Abstract

Primary signet-ring carcinoma is a very aggressive and rare variant of a primary urinary bladder cancer, accounting for less than 1% of cases. We reported on a 76-year-old patient with primary signet-ring carcinoma who occurred metastatic lymphadenopathy with extranodal invasion causing intraluminal tumor thrombi in the adjacent vein, and pulmonary metastasis over the course of three months. We demonstrated the computed tomography findings of primary signet-ring carcinoma of the bladder and correlated the imaging findings with the pathologic features. We reviewed the distinguishing imaging findings of the primary signet-ring carcinoma compared with urothelial cell carcinoma, the most common subtype of the bladder cancer.
