Approximately 15% of cases of renal cell carcinoma (RCC) present cystic configuration on radiologic and pathologic examination. The mechanisms of cyst formation in RCC are intrinsic multilocular cystic growth (multiloculated renal cell carcinoma: MCRCC), unilocular cystic growth (cystadenocarcinoma), cystic necrosis and tumor growth from the epithelial lining of a preexisting cyst. These cystic lesions accompanying RCC are often difficult to differentiate from the multiloculated renal cyst (MLC) or other benign cystic lesions such as hemorrhagic cyst and so on. Differential diagnosis of the complicated renal cystic lesions is discussed in this review.
约15%的肾细胞癌（RCC）病例在影像学和病理学检查中呈现囊性结构。RCC中囊肿形成的机制包括内在的多房性囊性生长（多房性肾细胞癌：MCRCC）、单房性囊性生长（囊腺癌）、囊性坏死以及源自先前存在囊肿上皮内衬的肿瘤生长。这些伴随RCC的囊性病变通常难以与多房性肾囊肿（MLC）或其他良性囊性病变如出血性囊肿等相鉴别。本文综述讨论了复杂肾囊性病变的鉴别诊断。
