Parapelvic cysts are uncommon conditions that are usually found during autopsy. Their ultrasonographic appearance is similar to hydronephrosis. We report the case of a 46-year-old female with a 4-year history of vague flank pain and a previous history of bilateral moderate hydronephrosis. The patient was investigated by ultrasonography and non-enhanced CT scan, and finally diagnosed as bilateral parapelvic cysts by a contrast-enhanced CT scan. For any patient with hydronephrosis detected by sonography, the possibility of parapelvic cysts should be kept in mind, especially if no underlying cause is detected and other routine imaging is inconsistent with hydronephrosis. In such circumstances a CT scan with contrast enhancement should not be refused, and relying on sonographic signs, previously mentioned in literatures, can be misleading.
肾盂旁囊肿是一种罕见疾病，通常在尸检时发现。其超声表现与肾积水相似。我们报告一例46岁女性病例，该患者有4年的模糊侧腹痛病史，既往有双侧中度肾积水病史。患者接受了超声检查和非增强CT扫描，最终通过增强CT扫描诊断为双侧肾盂旁囊肿。对于超声检查发现肾积水的任何患者，应考虑肾盂旁囊肿的可能性，特别是在未发现潜在病因且其他常规影像学检查结果与肾积水不符的情况下。在这种情况下，不应拒绝进行增强CT扫描，仅依靠文献中先前提到的超声征象可能会产生误导。
