Renal masses are commonly detected during imaging of the kidneys. It has been estimated that over half of patients over the age of 50 years harbor at least one renal mass, most commonly a simple cyst. In particular, most of renal masses are discovered incidentally when an imaging examination is performed to evaluate a nonrenal complaint. Although most represent benign renal cysts, not all incidental renal masses are benign, and most renal cell carcinoma (RCC) are also incidentally discovered in this scenario. Therefore, differentiating incidental benign renal masses from those that are potentially malignant is the most important challenge in daily practice.

Clear cell-type RCC is the most frequent variant, accounting to 80 % of all cases of renal tumors. Most clear cell RCC are solitary cortical neoplasms that occur with equal frequency in either kidney; multicentricity (4 %) and bilaterality (0.5–3.0 %) may be seen. Clear cell-type RCC has a worse prognosis compared with other histologic subtypes.

【CT of the Retroperitoneum- Renal Masses 腹膜后的CT检查---肾脏的肿块】
肾脏肿块在肾脏的影像检查中十分常见。据估，约半数超过50岁的患者，至少会有一个肾脏肿块，最常见的就是单纯的肾囊肿。尤其是，大多数肾脏肿块都是在评估其他非肾脏疾病的影像检查时偶然发现的。虽然大多数为良性的肾囊肿，但也不是所有偶然发现的肿块都是良性，大多数肾细胞癌也是通过这种方式发现的。因此，对于偶然发现的肾脏肿块，鉴别其是良性还是恶性对我们来说在日常工作中非常重要，也是一个挑战。
肾透明细胞癌是最常见的一种类型，约占肾脏肿瘤的80%。大多数肾透明细胞癌表现为单发的肾皮质肿块，双肾发病几率相同。4%的病灶表现为多中心，0.5-3%累及双肾。和其他组织亚型相比，肾透明细胞癌预后较差。
