【摘要】 目的:研究以急性腹痛就诊的系统性红斑狼疮(SLE)相关性肠病MSCT表现。方法:搜集2009年3月-2012年9月以急性腹痛入院并确诊为SLE者11例。所有患者均行MSCT双期增强扫描并对扫描图像进行图像后处理,由两位经验丰富的临床放射科医师观察双期增强扫描的轴面及后处理图像,研究SLE相关性肠病MSCT表现。结果:肠管:肠壁肿胀、增厚者10例(10/11),肠管表现为"靶征"和"双晕征"8例(8/11),肠壁囊样积气症1例(1/11)。肠管扩张9例(9/11),积气及积液者1例。肠系膜:肠系膜局部脂肪密度升高者9例(9/11),肠系膜血管增多、充血增粗者6例(6/11),肠系膜呈"梳状征"6例。胸水7例,腹腔积液10例,肠系膜及腹膜后淋巴结增多8例,双肾积水2例,膀胱壁增厚1例,SLE药物性肝损害1例。结论:SLE相关性肠病主要表现为肠壁和肠系膜改变。更多还原

【Abstract】 Objective:To evalute the MSCT findings of systemic lupus erythematosus(SLE)associated enteropathy in patients with acute abdominal pain.Methods:11SLE patients with acute addominal pain were collected in this study from March,2009 to September,2012.All patients received dual-phasic contrast-enhanced MSCT scan and image postprocessing.Two clinical radiologists analyzed the MSCT axial and postprocessing images to analyze the manifestation of lupus-associated enteropathy.Results:Intestinal wall swelling and thickening were seen in 10patients(10/11), "target sign" and "doublehalo sign" 8patients(8/11),pneumatosis cystoides intestinalis in one patient(1/11),bowel lumen dilatation in 9patients(9/11)with one patient of pneumatosis and effusion,focal increased mesenteric fat attenuation 9patients(9/11),increased and thickened mesenteric vessels 6patients(6/11),mesenteric comb sign 6patients(6/11),hydrothorax 7patients,ascites10 patients,mesenteric and retroperitoneal lymphadenopathy 8patients,hydronephrosis 2patients,bladder wall thickening 1patient.SLE-induced liver damage 1patient.Conclusion:The main MSCT findings of lupus-associated enteropathy are the changes of intestinal wall and mesenteric vasculature.更多还原
