Abstract:
Renal cell carcinoma (RCC) is an aggressive carcinoma with hematogenous spread commonly to lungs, liver, and bones. However, few cases of isolated urinary bladder metastasis have also been reported. Here we report a case of 63-year-old man, a known case of left RCC (clear cell type), post left nephrectomy, who was on regular clinicoradiological follow-up. He presented with complaints of painless hematuria; on further evaluation, 18F-FDG PET/CT revealed few FDG-avid intramural nodular lesions along the walls of urinary bladder. He underwent TURBT, and the tissue was sent for histopathological examination, which was diagnostic of metastatic RCC.
