Urothelial Bladder Cancer With Cardiac Metastasis: A Case Report.

We report a case with a large muscle-invasive bladder TCC and cardiac and disseminated metastases. A 74-year-old man was referred to our department due to a decline in general health, associated with macroscopic hematuria for the past two months, in the context of urinary infection. CT imaging revealed a large bladder tumor with bilateral hydronephrosis, suspicion of peritoneal carcinomatosis, and locoregional lymphadenopathies suggesting secondary involvement. Histology of the bladder tumor confirmed the diagnosis of high-grade infiltrating urothelial carcinoma. The 18-FDG PET scan detected diffuse lymph node, hepatic, and bone metastases, as well as peritoneal carcinomatosis and metastases in the left ventricle and atrium. Chemotherapy was planned for our patient; unfortunately, the patient passed away rapidly due to renal and cardiac complications before treatment could begin.
