In a review of abdominal CT in patients with adult polycystic kidney disease 24 patients were found to have single or multiple high density renal cysts on nonenhanced studies. All cases showed well defined, homogeneous high density cysts (56-98 HU), with smooth contours, sharp interfaces with renal parenchyma, and lack of contrast enhancement. The benign nature of these lesions was established by tissue examination in five patients and follow-up CT in four others. In the remaining 15 patients the benign nature of these lesions was assumed based on the constellation of CT and clinical findings.
在一项针对成人多囊肾病患者的腹部CT回顾研究中，发现24例患者在非增强扫描时有单个或多个高密度肾囊肿。所有病例均显示边界清晰、密度均匀的高密度囊肿（56 - 98 HU），轮廓光滑，与肾实质界面清晰，且无强化表现。其中5例患者通过组织检查，另外4例通过CT随访证实了这些病变的良性性质。其余15例患者则根据CT表现和临床症状综合判断为良性病变。
