Abstract
The incidence of renal malignancy increased dramatically during the past few decades ,renal cell carcinoma represents 3-4% of all malignancies worldwide, preoperative multiphasic CT imaging provide useful information regarding pathologic diagnosis in patients before selecting a treatment. The histologic type of RCC is one of the most important prognostic factors with clear cell RCC is the most common type.
