Abstract
目的提高对肾结核CT影像的认识及诊断水平.方法收集经手术病理证实的肾结核2 4例,分析其CT表现.结果肾结核的CT表现有(1)肾髓质多发空洞或脓腔形成(8 3.3%),呈囊状低密度影围绕相对狭小肾盂呈花瓣状排列;(2)肾皮质变薄(75.0%);(3)肾盂及输尿管壁增厚(66.7%),管腔狭窄与扩张并存;(4)结核性空洞洞壁、肾实质钙化及肾自截(58.0%);(5)肾盏轻度扩张,肾盏杯口面侵蚀破坏,相应肾髓质多发小脓腔(1 6.7%).而肾体积及外形改变、肾积水或积脓、肾功能不全为继发常见改变.结论肾结核CT特征表现为:断面上聚集成花瓣状多发低密度区,CT扫描对肾结核的诊断具有重要价值.
