Interesting, unusual, and confusing renal cysts from a group of 200 cysts punctured percutaneously during the past decade are presented. Some cases illustrate pressure phenomena in cysts adjacent to each other or causing calyceal obstruction. Also reported are cyst wall findings, unusual cyst configurations, infection in pre-existing cysts, examples of cysts simulating renal cell carcinoma, and renal cell carcinoma presenting as cysts. In unusual cases, percutaneous needle puncture remains the procedure of choice for establishing the diagnosis of benign simple cyst versus malignancy or infection, or for determining the relationship of a cyst with the collecting system or with other cysts. Cyst puncture may also result in iatrogenic changes.
本文呈现了过去十年间经皮穿刺的200个肾囊肿中有趣、不寻常且令人困惑的病例。一些病例展示了相邻囊肿间的压力现象或导致肾盏梗阻的情况。还报告了囊肿壁的表现、不寻常的囊肿形态、原有囊肿的感染、酷似肾细胞癌的囊肿实例以及表现为囊肿的肾细胞癌。在不寻常的病例中，经皮穿刺针吸活检仍是区分良性单纯囊肿与恶性病变或感染、确定囊肿与集合系统或其他囊肿关系的首选诊断方法。囊肿穿刺也可能导致医源性改变。
