目的探讨CT定位诊断胃肠道外间质瘤(extra-gastrointestinal stromal tumors,EGIST)的价值。方法回顾性分析13例经手术病理证实的EGIST患者的CT资料,重点观察病变的部位、大小、形态,病灶内有无气体、溃疡、钙化及坏死,邻近胃肠道黏膜有无破坏,以及病变与胃肠道血管弓及其属支血管的关系,并与23例经手术病理证实的外生性胃肠道间质瘤(gastrointestinal stromal tumors,GIST)对比。结果 13例EGIST患者中,发现气体及肠道黏膜破坏各1例,10例病变主体层面上肿瘤与胃肠壁之间显示胃肠壁血管弓及其属支血管,病变边缘未见拉直的血管弓属支血管。23例外生性GIST患者中,发现气体、溃疡和胃肠道黏膜破坏分别为10例、12例和20例,17例病变边缘有拉直的血管弓属支血管,血管弓被推离胃肠壁,病变与胃肠壁之间无血管弓及其属支血管显示(P<0.05)。结论根据肿瘤内有无气体、溃疡,胃肠道黏膜有无破坏及肿瘤与胃肠道血管弓及其属支血管的关系,CT可对EGIST做出定位诊断。
Objective To investigate the value of CT in the diagnosis of extra-gastrointestinal stromal tumors (EGIST). Methods The CT data of 13 patients with pathologically confirmed EGIST were retrospectively analyzed. The location, size and shape of the lesion, the presence of gas, ulceration, calcification and necrosis in the lesion, adjacent mucosa of the gastrointestinal tract, and lesions And the relationship between gastrointestinal bowel and its branches, and with 23 cases of pathologically confirmed gastrointestinal stromal tumors (GIST). Results In 13 cases of EGIST, gas and intestinal mucosal damage were found in 1 case. On the main body of 10 cases, the bowel and its branches of the gastrointestinal wall between the tumor and gastrointestinal wall showed no straightening Vascular arch is a branch of blood vessels. In 23 cases of exogenous GIST, gas, ulcer and gastrointestinal mucosal damage were found in 10 cases, 12 cases and 20 cases, 17 cases of strangulation at the edge of angiosperm vessels, vascular bow was pushed away from the gastrointestinal wall , There was no vascular bow between the lesion and gastrointestinal wall and its branches (P <0.05). Conclusion According to the presence or absence of gas, ulceration, gastrointestinal mucosa destruction and tumor and gastrointestinal bowel and its branches, CT can make a localization diagnosis of EGIST.
