We report a case of Bellini duct carcinoma with giant hydronephrosis. A 56-year-old man was referred with the chief complaint of gross hematuria. The intravenous pyelography showed a huge right renal contour and non-functioning kidney. The abdominal computed tomographic scan and magnetic resonance imaging demonstrated giant hydronephrosis. Percutaneous urinary cytology obtained in the direct pyelography was class V. Right total nephro-ureterectomy was performed. Punctured fluid volume was 1,010 ml during the operation. Histological and immunohistochemical analysis revealed the collecting duct carcinoma of the kidney. Three months later, multiple bone metastases had appeared. He was treated by the combination chemotherapy of gemcitabine and paclitaxel, but lung and liver metastases developed. The patient died of cancer 12 months later. This case was considered to be Bellini's duct carcinoma as its features had poor prognosis and image findings infiltrating from medulla to cortex with the total enlargement of the kidney. To our knowledge there has been no case found like these atypical imaging findings.
