摘要
目的探讨下段食管旁假性脂肪瘤(PLTP)影像特点。方法搜集PLTP 18例(8例同时作了上消化道造影GI和MSCT检查),分析其GI和MSCT表现。结果 5例GI显示下段食管右侧较大软组织影,密度浅淡,粘膜相粘膜粗乱,1例幕状拉吊;充盈相食管腔稍窄,壁较柔软,移位不明显,病变上界常可见;3例His角圆钝,1例随体位变化,1例滑动性裂孔疝胃泡突入PLTP中;3例GI基本正常;18例MSCT示裂孔区食管旁脂肪囊影,内见点条状血管影;MPR脂肪囊下部呈狭颈状,与腹腔脂肪相连,胃左动脉弓状指向或突入食管裂孔。结论食管裂孔区食管旁密度浅淡软组织影、粘膜和管腔改变轻,上缘见边界,食管无移位及His角圆钝,是PLTP的GI特点;脂肪囊与腹腔脂肪相连伴胃左动脉弓状指向或突入食管裂孔为MSCT特点。
Objective To explore the image characteristics of pseudo-lipomatous tumor paraesophageal(PLTP).Methods A total of 18 cases of PLTP were collected,of which 8 were examined by GI(Upper gastrointestinal barium contrast medium)and MSCT simultaneously,the comparative analysis of GI and MSCT was performed.Results There were 5 cases GI showed the soft tissue shadow on the right side of the lower esophagus,with lower dentist and esophageal mucous disorder at mucous phase,was showed coarse disorderly in the mucous membrane phase.Filling phase showed a slightly narrow esophageal cavity,with soft wall,no displacement and visible upper boundary.3 case with obtuse His angle,Of which one case its change with position.3 cases with almost normal GI manifestion,1 case of sliding hiatal hernia the stomach protruded into PLTP.A cystic fat density shadow was showed by MSCT right paraesophagus above hiatus in18 cases.The connection of the lower part of cystic fat density shadow to abdominal fat was showed all in 18 cases by MPR,and left gastric artery was shown to point to or protrud into hiatus by arcuate or straight form.Conclusion A larger fade soft tissue density shadow above the hiatus paraesophageal,with slight change of mucous membrane and lumen of lower segment esophagus which no obviously shifted and with His angle obtuse variable were the characteristic GI performance of PLTP.The fat capsulethe connected with abdominal fat with left gastric artery shown to point to or protrud into hiatus by arcuate or straight form was the image characteristics of MSCT.
