大肠埃希菌致肾周围脓肿的MSCT表现及临床价值

摘要

目的 探讨大肠埃希菌致肾周围脓肿的MSCT表现及临床价值.方法 回顾性分析自2007年1月～2016年11月期间我院资料完整的12例大肠埃希菌感染致肾周围脓肿的CT表现,观察其病变范围、边界、内部分隔及强化特点,并分析临床价值.结果 12例肾周围脓肿CT表现为病变均包绕患侧肾脏;局限型3例,弥漫型9例;累及腹腔内3例,累及患侧腰肌、腹后壁5例、沿肌肉间隙蔓延6例.增强后病灶环状强化,表现为大单房或大的多房脓腔,分隔少,腔内见气体.结论 大肠埃希菌感染致肾周围脓肿MSCT表现为病变范围大,周围组织受累重,部分腔内积气.MSCT能为临床诊治提供客观依据,具有重要的临床价值.%Objective To explore the clinical value and significance of MSCT in the diagnosis of perinephric abscess induced by Escherichia coli.Methods We retrospectively analyzed the CT findings of 12 cases of perinephric abscess by Escherichia coli infection in our hospital from January 2007 to November 2016,observed the extent of disease,border,internal separation and strengthening characteristics,and analyzed the clinical value.Results CT manifestations of the lesion in those 13 cases are wrapped around the ipsilateral kidney.The lesions were localized in 3 cases,diffuse in 9 cases,involving the abdominal cavity in 3 cases,involving the ipsilateral psoas muscle and abdominal wall in 5 cases.The lesions wree ring enhancement after the enhanced CT,which manifested as large single room or large multi-room abscess,separated by small,cavity with the gas.Conclusion MSCT findings of perinephric abscess caused by Escherichia coli infection showed a wide range of lesions,the surrounding tissue involvement of heavy,part of the cavity gas accumulation.MSCT can provide an objective basis for clinical treatment,which has an important clinical value.
