目的:探讨胃肠道间质瘤的超声表现特征。方法:搜集经手术病理和免疫组化证实的胃肠道间质瘤患者9例,对其超声表现进行回顾性分析。结果:(1)肿瘤位于胃4例,十二指肠1例,小肠2例,结肠1例。瘤体最大12cm,最小3.5cm。(2)超声检查发现胃肠道实性肿块4例,囊实性肿块5例。(3)病理检查其中良性5例,恶性及恶性潜能4例。结论:对胃肠道间质瘤早期发现,超声检查能提高其检出率。
Objective: To investigate the ultrasound features of gastrointestinal stromal tumors. Methods: Nine patients with gastrointestinal stromal tumors confirmed by pathology and immunohistochemistry were collected for retrospective analysis. Results: (1) The tumor was located in stomach in 4 cases, duodenum in 1 case, small bowel in 2 cases and colon in 1 case. The largest tumor 12cm, the smallest 3.5cm. (2) Ultrasonography found 4 cases of gastrointestinal solid mass, 5 cases of cystic mass. (3) pathological examination in which benign in 5 cases, 4 cases of malignant and malignant potential.
