| 摘 要： | 目的:分析胃肠道间质瘤的影像学表现。方法:对16例经病理学证实为胃肠道间质瘤患者进行不同的影像学检查。结果:16例原发胃肠道间质瘤中原发于胃10例,原发于十二指肠1例,发生于回盲部1例,发生于小肠2例,横结肠系膜1例,乙状结肠系膜1例。内生性生长者1例,外生性生长者11例,腔内外生长者1例。影像学判断GIST良恶性的符合率为81%(13/16)。结论:外生性生长是胃肠道间质瘤主要的生长方式,也是诊断的主要依据。CT是该病术前诊断及判断其生物学行为的主要工具。

| Abstract: | Objective:To analyze imaging features of gastrointestinal stromal tumors (GIST).Methods:16 patients with GIST confirmed by pathology underwent various imaging examinations.Results:16 cases of GIST (10 cases in stomach,1 case in duodenum,1 case in ileocecum,2 cases in small bowel,1 case in transverse mesocolon,1 case in sigmoid mesentery) including 11 exophytic masses,1 endophytic mass,and 1 exo- and endophytic mass were studied.Among them,1 case had hepatic metastasis.The concordance rate for CT with pathological results was 81%.Conclusion:The exophytic mass is the main growth pattern and the main basis of diagnosis as well.CT is the main tool for preoperational diagnosis and definition of its biological behavior. |
