Renal Cell Carcinoma: Interactive CT Case Study

Editor: Richard Lindsey

November 26, 2014

Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies and 90-95% of neoplasms arising from the kidney. It is characterized by a lack of early warning signs, diverse clinical manifestations, and resistance to radiation and chemotherapy. Contrast-enhanced computed tomography (CT) is the imaging procedure of choice for diagnosis and staging of RCC. In most cases, CT can differentiate cystic masses from solid masses and supply information about lymph node, renal vein, and inferior vena cava involvement. The probability of cure is directly related to the stage or degree of tumor dissemination: More than 50% of patients with early-stage RCC are cured, but the outcome for stage IV RCC is poor.
