目的探讨影像学检查对胃肠道间叶组织肿瘤的诊断价值。方法回顾性分析31例经手术病理证实的胃肠道间叶组织肿瘤的影像学表现。结果31例胃肠道间叶组织肿瘤中,间质瘤14例,平滑肌源性肿瘤9例,淋巴瘤7例,神经鞘瘤1例。其中良性11例,恶性20例。病变部位胃21例(68%),小肠、结肠9例(29%),其他1例(3%);大小<5cm×5cm14例(45%),>5cm×5cm17例(55%);生长方式位于腔内9例(29%),腔内外均有17例(55%),腔外5例(16%);形态肿块呈圆形、类圆形20例(65%),不规则形11例(35%);胃肠钡剂检查示胃肠道局部黏膜受压移位并出现软组织肿块,形成溃疡及气液平面;CT不仅可以反映肿块的密度、边缘、增强等改变,还可反映恶性间叶组织肿瘤淋巴结及肝脏转移情况;MRI提示病变区异常信号,特别能反映囊变的情况。结论影像学检查对胃肠道间叶组织肿瘤的诊断有很大的价值。
Objective To investigate the diagnostic value of imaging examination for gastrointestinal mesenchymal tumor. Methods The imaging findings of 31 patients with gastrointestinal mesenchyme confirmed by surgery and pathology were retrospectively analyzed. Results Of the 31 patients with gastrointestinal mesenchymal tumors, 14 were stromal tumors, 9 were smooth muscle-derived tumors, 7 were lymphomas and 1 was schwannoma. Among them, 11 cases were benign and 20 cases were malignant. The lesions were located in 21 cases (68%) in the stomach, 9 cases (29%) in the small intestine and colon and 1 case (3%) in the other 5 cases. There were 9 cases (29%) in the cavity, 17 cases (55%) in the cavity and 5 cases (16%) in the cavity. The shape of the tumor was round, 20 cases (65% 11 cases (35%); gastrointestinal barium showed gastrointestinal mucosal pressure shift and the emergence of soft tissue mass, the formation of ulcers and gas-liquid level; CT can not only reflect the density of the tumor, the edge, enhance and other changes, but also Reflect the malignant mesenchymal tumor lymph nodes and liver metastases; MRI tips abnormal signal lesions, in particular, can reflect the situation of cystic degeneration. Conclusion Imaging diagnosis of gastrointestinal mesenchymal tumor has great value.
