摘　　要：目的观察消化道间质瘤消化钡餐、多层螺旋CT(MSCT)影像学表现,并与病理学特征进行对照比较。方法选取本院2017年3月至2020年2月收治且经手术病理确诊32例食管间质瘤患者作为研究对象。观察肿瘤部位、大小、形态、有无囊性变及转移等影像学特征。结果32例食管间质瘤经手术病理证实食管良性间质瘤26例,食管恶性间质瘤6例。13例食管良性间质瘤,均为单发病灶。钡餐可见规则的充盈缺损。黏膜连续通过压迹影,管壁柔软。CT平扫表现为软组织密度影,边界清楚,增强扫描动脉期、静脉期均无明显强化。6例食管恶性间质瘤,单发病灶4例,多发病灶2例。消化钡餐扫描肿瘤呈外压性改变,2例肿瘤表面粗糙,管壁坚硬,管腔有明显狭窄。CT平扫肿瘤呈融合状,密度不均匀,增强扫描可见明显囊性变,强化明显。32例食管间质瘤均未见肿大淋巴结。其中6例食管恶性间质瘤中1例出现多发肝脏转移。结论MSCT检查与消化钡餐均可清晰显示食管间质瘤的影像学特征,与病理学特征吻合度高,可为临床治疗食管间质瘤提供可靠的指导意见。Objective To observe the barium meal and multi-slice spiral CT(MSCT)imaging manifestations of esophageal stromal tumors,and compare them with pathological features.Methods 32 patients with esophageal stromal tumor diagnosed in our hospital from March 2017 to February 2020 were selected as the research objects.The imaging features such as the location,size,shape,and cystic changes and metastases were observed.Results In 32 cases with esophageal stromal tumors,26 cases were diagnosed as benign stromal tumors of the esophagus by surgical pathology and 6 cases as esophageal malignant stromal tumors.13 cases with benign stromal tumors of the esophagus were all single lesions.Barium meal showed regular filling defects.The mucosa continuously passes through the impression shadow,and the tube wall was soft.The plain scan of CT showed the density shadow of soft tissue with clear boundaries,and there was no obvious enhancement in the arterial and venous phases of enhanced scanning.There were 6 cases with esophageal malignant stromal tumors,including 4 cases with single lesion and 2 cases with multiple lesions.The scan of the barium meal showed changes by external pressure in tumors.The surface of two tumors was rough,the tube wall was hard,and the lumen was significantly narrowed.CT plain scan showed that the tumor was fused and uneven in density.Enhancement scans showed significant cystic changes and significant enhancement.The swollen lymph nodes were not found in 32 patients with esophageal stromal tumors.In the 6 cases with esophageal malignant stromal tumors,one patients had multiple liver metastases.Conclusion MSCT examination and barium meal can clearly show the imaging characteristics of esophageal stromal tumors,which is in good agreement with pathological characteristics,and can provide reliable guidance for clinical treatment of esophageal stromal tumors.
