Peripelvic cysts can closely mimic the sonographic changes of renal pelvicalyceal dilatation. Three cases are described in which a particular feature was the presence of linear septations extending to the hilum which represented the walls of tubular peripelvic cysts. The cluster of cysts centrally in the renal sinus was originally interpreted as a dilated pelvicalyceal system. Excretion urography is usually necessary to exclude pelvicalyceal dilatation conclusively.
肾周囊肿可酷似肾盂肾盏扩张的超声表现。本文描述了3例病例，其特征性表现为线状分隔延伸至肾门，代表肾小管性肾周囊肿的壁。最初，肾窦中央的囊肿群被误诊为肾盂肾盏扩张。通常需要进行排泄性尿路造影以最终排除肾盂肾盏扩张。
