探究胃肠道间质瘤的CT影响特征。回顾性分析5例经过手术病例和免疫组化证实的胃肠道间质瘤病患的CT检查资料。发现有5例胃肠道间质瘤根据肿块生长方式不同分为附壁腔外生长型1例、跨壁生长型3例、腔内生长型1例;其中有两例瘤内出现钙化灶;胃肠道间质瘤瘤内容易发生黏液变、坏死液化或者出血从而导致瘤密度及其不均匀。逐渐增强CT期扫描瘤体延时强化更加显著,而且肿瘤内部黏液变区增强后轻度强化,瘤内坏死液化区不强化,通过这两者不同现象可以加以鉴别。因而我们可以通过病例分析,能够看出大多数胃肠道间质瘤以外生性为主,瘤体内血液丰富,黏液变、坏死液化、出血及钙化现象很常见。所以仔细观察研究以及深入分析胃肠道间质瘤CT影像特征,对于术前诊断有很大的帮助。
To explore the CT features of gastrointestinal stromal tumors. Five cases of gastrointestinal stromal tumors confirmed by surgery and immunohistochemistry were retrospectively analyzed. Found in 5 cases of gastrointestinal stromal tumors according to the different growth of the tumor is divided into ancillary growth in 1 case, transmembrane growth in 3 cases, intracavitary growth in 1 case; of which there are two cases of calcification within the tumor; Gastrointestinal stromal tumor prone to mucus change, necrosis liquefaction or bleeding resulting in tumor density and its uneven. Increasing CT scan of the tumor delayed enhancement is more significant, and the tumor mucosal change area enhanced slightly enhanced, the necrosis of the liquefied area is not enhanced, through the two different phenomena can be identified. Therefore, we can through case analysis, we can see that most of the gastrointestinal stromal tumors in vitro-based, rich in blood tumor, mucus change, necrosis liquefaction, bleeding and calcification are common. So careful observation of the study and in-depth analysis of gastrointestinal stromal tumor CT imaging features, for preoperative diagnosis of great help.
