Cystic nephroma is a rare kidney neoplasm belonging to the entity of cystic tumours. It is a slow-growing tumour, which develops insidiously, sometimes reaching a considerable size. The diagnosis is more often accidental (except for mass syndrome in children). It is a benign tumour that may be treated by partial sparing nephrectomy. Malignant degeneration is few and far between. However, no medical examination can confirm the diagnosis before surgery. On medical imaging, the tumour enhances after contrast injection and there will always be a doubt about the benignity. Furthermore, percutaneous biopsy of the mass is not contributory to the diagnosis. This means that it is not easy to propose a conservative surgical treatment, even though this remains the best way to deal with such a tumour.
囊性肾瘤是一种罕见的肾脏肿瘤，属于囊性肿瘤范畴。它是一种生长缓慢的肿瘤，隐匿性生长，有时可长得相当大。诊断多为偶然发现（儿童出现肿块综合征除外）。它是一种良性肿瘤，可通过保留肾单位的部分肾切除术进行治疗。恶性变极为罕见。然而，术前没有任何医学检查能够确诊。在医学影像上，肿瘤在注射造影剂后会强化，其良性与否始终存疑。此外，对肿块进行经皮活检无助于诊断。这意味着即便保留肾单位的手术仍是处理此类肿瘤的最佳方式，但要提出保守的手术治疗方案并不容易。
