【摘要】：目的探讨嗜酸性粒细胞性胃肠炎(EG)的多层螺旋CT(MSCT)特征及其诊断价值。资料与方法回顾性分析12例经胃肠镜及病理活检证实的EG患者的临床及影像资料,按照临床分型、病变的浸润部位及深度等总结其MSCT特征。结果12例EG中黏膜型7例,其中胃部受累5例,CT所见胃壁增厚、水肿,黏膜下假息肉状结节影;肠道受累2例,空肠"羽毛状"黏膜皱襞增粗呈锯齿状改变。肌型少见,回盲部1例,肠壁增厚、僵硬伴肠腔狭窄,似肿块样改变。浆膜型1例,浆膜面毛糙,直小血管增粗,肠周纤维脂肪增粗并见少量腹水。混合型3例,多段肠道呈单型或多型浸润,跳跃式发展,肠道壁分层、多环状强化,提示黏膜和黏膜下层病变与浆膜层病变共存。结论 EG的每型均有其特征性MSCT表现,结合外周血嗜酸性粒细胞增多,可为临床诊断本病提供客观的影像诊断学和分型依据,临床可以依据EG的分型、累及范围采取合理的治疗方式,对随访评估有重要意义。
[Abstract]:Objective to investigate the characteristics and diagnostic value of multilayer spiral CTT (MSCT) in eosinophil gastroenteritis (EGG). Materials and methods the clinical and imaging data of 12 patients with EG confirmed by gastroenteroscopy and pathological biopsy were analyzed retrospectively. The MSCT features of EG patients were summarized according to clinical classification, location and depth of infiltration. Results among 12 cases of EG, 7 cases were mucosal type, of which 5 cases had gastric wall thickening, edema and submucosal pseudopolypoid nodular shadow, and 2 cases had intestinal involvement, and the thickening of jejunum "feather" mucosal fold was serrated. Muscle type was rare, ileocecal part in 1 case, intestinal wall thickening, rigid with intestinal lumen stenosis, tumor-like changes. Serosal type in 1 case, serosal surface was rough, straight small vessels thickened, periintestinal fiber fat thickened and a small amount of ascites. In 3 cases of mixed type, the multiple intestinal tract showed a single or multi-type infiltration, leaping development, intestinal wall stratification, multi-ring enhancement, suggesting the coexistence of mucosal and submucosal lesions and serosal lesions. Conclusion each type of EG has its own characteristic MSCT features. Combined with the increase of eosinophil in peripheral blood, EG can provide objective imaging diagnosis and classification basis for clinical diagnosis of EG, and can be based on the classification of EG in clinic. It is of great significance to follow up and evaluate the extent of involvement by adopting reasonable treatment.
