【摘要】：目的探讨小肠肿瘤及肿瘤样病变患者的病理特征及其CT表现。方法回顾性分析本院2013年2月-2016年2月经手术病理证实的60例小肠肿瘤及肿瘤样病变患者的临床资料,比较观察不同肿瘤、瘤样病变病理特征及CT表现。结果病理检查显示60例患者中恶性肿瘤5例,良性肿瘤35例,肿瘤样病变20例,均呈现息肉状且往肠腔内突出特点;胃肠道间质瘤病灶在黏膜下,梭形肿瘤细胞,排列走向不一;脂肪瘤也位于黏膜下,黏膜表面溃疡,肿瘤切面黄色;淋巴组织增生镜下显示黏膜层存在病灶,细胞分化成熟。CT对小肠肿瘤、肿瘤样病变检出率均为90.00%,腺癌CT增强扫描呈现"快速上升-平台"特点;小肠淋巴瘤CT表现为肠壁增厚、肠管狭窄、腹膜及肠系膜淋巴结肿大;胃肠道间质瘤以腔外生长为主,圆形或椭圆形,病灶与周边正常肠壁边界清楚。结论小肠肿瘤以良性肿瘤为主,病理特征、CT表现在小肠肿瘤及肿瘤样病变诊断中有重要价值。
[Abstract]:Objective to investigate the pathological features and CT findings of small intestinal tumors and tumor-like lesions. Methods 60 cases of small intestinal tumors and tumors proved by surgery and pathology from February 2013 to 2016 were retrospectively analyzed. Clinical data of patients with like lesions. Results pathological examination showed that there were 5 cases of malignant tumor, 35 cases of benign tumor and 20 cases of tumor-like lesion. All of them showed polypoid and protruding into the lumen. Gastrointestinal stromal tumors (GIST) with submucous and fusiform tumor cells are arranged in different directions. Lipoma is also located in the submucous membrane, mucosal surface ulcer, tumor section yellow; Lymphoproliferative examination showed that there were lesions in mucosal layer. The detectable rate of tumor-like lesions was 90.00% for small intestinal tumors with mature cell differentiation. The CT enhanced scan of adenocarcinoma showed the characteristics of "rapid rise-platform". Ct findings of small intestinal lymphoma included thickening of intestinal wall, stenosis of intestinal duct and enlargement of peritoneal and mesenteric lymph nodes. Gastrointestinal stromal tumors (GIST) are mainly extraluminal, round or oval, and the boundary between the lesions and the surrounding normal intestinal wall is clear. Conclusion small intestinal tumors are mainly benign tumors, pathological characteristics. Ct findings are of great value in the diagnosis of small intestinal tumors and tumor-like lesions.

【正文快照】： 小肠具有长度长、走向曲折、活动度大特点,因此小肠肿瘤临床少见,在消化道肿瘤中仅占1%~4%[1]。大部分小肠肿瘤患者经手术治疗后早期治愈率高,为此早期诊断出小肠肿瘤对其治疗方案制定、预后改善具有十分重要的意义[2]。由于小肠肿瘤早期症状无特异性,且X线、小肠镜检查对黏膜
