摘要
目的：探讨肾钙乳的影像学表现及CT诊断价值。方法：对12例肾钙乳患者行常规腹部X线立位正、侧位片及螺旋CT平扫,其中3例行增强扫描。采用双盲法由2位影像科医生共同阅片。结果：CT图像均清晰显示肾钙乳囊肿全貌及＂半月征＂,半月形高密度影始终位于病灶最低点。其中囊肿型5例,积水型7例;单侧病变10例,双侧2例。肾钙乳合并肾结石2例。常规X线诊断肾钙乳6例,误诊为肾结石4例,漏诊2例。结论：螺旋CT对肾钙乳诊断具有重要价值,其敏感性明显优于常规X线检查。
Objective：To evaluate CT in diagnosis of renal milk of calcium（RMC）.Methods：The X-ray films and CT findings of 12 cases of RMC were reviewed by two experienced radiologists by double blind method.All the cases underwent anterior-posterior and lateral abdomen plain film examination and non-enhanced CT scans.Among them,3 cases were performed enhanced CT scan.Results：The CT findings clearly displayed the whole view of milky calcium cyst and its＇half-moon＇sign.The half-moon＇s high density shadow formed by RMC was always located in the lowest part of the lesion.The cyst type and hydronephrosis type were observed in 5 cases and 7 cases respectively;the lesions of all but 2 cases were unilateral;RMC accompanied by renal stone was found in 2 cases.Four cases of RMC were misdiagnosed as renal stone and 2 cases were miss-diagnosed by X-ray.Conclusions：CT plays an important role in diagnosis of stone and its sensitivity is superior to X-ray films.
