摘要
目的旨在探讨多排螺旋CT增强扫描对肾脓肿并肾周感染的诊断价值。方法选取我院2016年1月-2018年5月收治的经手术或CT扫描检查证实的肾脓肿并肾周感染患者48例,所有患者均进行多排螺旋CT平扫及增强扫描,整理58例患者的临床及影像学资料,根据其CT扫描图像对其特点进行分析,评估其诊断价值。结果58例患者中,35例为单发,23例为多发,其中右侧发病31例,左侧发病27例。病灶大小约为2.03mm^6.17mm。CT扫描示:病灶部位平扫呈等密度、稍低低密度,形态多为楔形、圆形或类圆形;增强扫描后可见肾实质呈圆形或弧形缺损且肾盂肾盏受病灶压迫呈现出弧形移位。部分患者可于增强扫描后于病灶周边见轻度强化的环状影,且与周围的一圈低密度带形成典型的"双环征"或"月晕征"。结论多排螺旋CT增强扫描对肾脓肿并肾周感染进行扫描,能根据图像直观、全面的准确显示肾脏的病变部位,有利于临床对病变的精准定位。
Objective To explore the diagnostic value of multi-slice spiral CT enhanced scan for renal abscess and perirenal infection.Methods Forty-eight patients with renal abscess and perirenal infection confirmed by surgery or CT scan from January 2016 to May 2018 in our hospital were selected.All the patients received multi-slice spiral CT scan and enhanced scan.The clinical and imaging data of 58 patients were collected.According to the image of CT scan,their characteristics were analyzed.Results Among the 58 patients, 35 cases were single and 23 cases multiple,including 31 cases on the right side and 27 cases on the left side.The lesion size was about 2.03mm-6.17mm.CT scanning showed that the lesions were of equal density,slightly low and low density,and most of them were wedge-shaped,circular or quasi-circular.After the enhanced scan,the renal parenchyma presented a circular or arcuate defect and the renal pelvis and renal calyces were compressed by lesions,showing arcuate displacement.Some patients may can be seen with slightly enhanced annular shadow around the lesion after enhanced scanning,and form typical "double ring" or "halo" sign with the surrounding low-density zone.Conclusion The multi-slice spiral CT enhanced scan for renal abscess and peritoneal infection can accurately and comprehensively show the pathological site of the kidney according to the image,and have specific scanning signs,which is conducive to the precise localization of the pathological changes in clinic.
