摘要
目的分析小肠间质瘤(GIST)的CT表现特点、探讨CT对该瘤定位、定性诊断价值。方法搜集经手术病理证实21例小肠间质瘤的病例资料进行回顾分析。结果十二指肠6例,空肠8例,回肠7例;良性2例,低度恶性5例,恶性14例;CT表现为肠壁单发偏心性肿块,腔外16例、腔内5例,大小3～15 cm;2例良性和3例低度恶性呈类圆形、边界清楚、密度均匀、小于4 cm;19例恶性GIST中,不均匀16例,有多灶性坏死、碘水进入显示液平2例,合并腹腔脓肿1例,边缘边界不清15例,分叶13例,15例大于4 cm,腹膜后淋巴结转移1例,肝转移1例;增强后良性均匀较明显强化、恶性肿瘤实体部分明显强化。结论 CT对小肠GIST的诊断有重要价值,其定位、定性的准确率高,对临床的早期诊断和治疗和重要意义。
Objective Analysis of intestinal stromal tumors（GIST） of the performance characteristics of CT, CT to explore the tumor location, the value of diagnosis. Methods to collect by surgery and pathology confirmed 21 cases of intestinal stromal tumor cases were retrospectively analyzed. Results Six cases of the duodenum, jejunum 8 cases, 7 cases of ileum; 2 cases of benign, low- grade 5, 14 cases of malignant; CT performance for the single wall eccentric mass, 16 cases outside the chamber, the cavity 5, the size of 3 - 15 cm; 2 patients with benign and low- grade 3 were round, clear boundary, uniform density, as smaller than 4 cm; 19 cases of malignant GIST, 16 cases of non - uniform, a number of focal necrosis, iodine water Into the fluid level in 2 cases showed that the combined intra - abdominal abscess in 1, the edge of 15 cases of unclear border, leaves at 13 cases, 15 cases as bigger than 4 era, retroperitoneal lymph node 1, 1 case of liver metastases; enhanced significantly strengthen more evenly benign and malignant Significantly strengthen the physical part of the tumor. Conclusion CT diagnosis of GIST of the small intestine of great value, and its position as the high accuracy of clinical diagnosis and early treatment and significance.
