目的:探讨胃间质瘤的CT表现,以提高诊断正确率。方法:收集经过病理检查证实的12例胃间质瘤患者的临床资料,对患者行16层CT平扫和双期增强检查的结果进行分析。结果:12例胃间质瘤向腔外生长者3例,向腔内生长者6例,同时向腔内、腔外生长者3例;肿瘤多垂直胃壁生长且境界清晰或较清晰。6例良性肿瘤直径多小于5 cm并多向腔内生长,增强扫描多为轻、中度强化;6例恶性肿瘤直径均大于5 cm,多向腔外或同时向腔内、腔外生长,增强扫描多为中度、明显强化。结论:胃间质瘤CT表现有一定特征,有重要诊断价值,不典型病例仍需依靠病理诊断。
Objective: To investigate the CT findings of gastric stromal tumors in order to improve the diagnostic accuracy. Methods: The clinical data of 12 patients with gastric stromal tumors confirmed by pathology were collected. The results of 16-slice CT plain scan and double-phase enhanced examination were analyzed. Results: Of the 12 cases of gastric stromal tumors, 3 were extracavitary and 6 were intracavitary, while 3 were extracavitary and 3 extracapsular. The tumor grew vertically with clear or clear border. 6 cases of benign tumors more than 5 cm in diameter and more to the growth of the cavity, enhanced scan mostly mild and moderate enhancement; 6 cases of malignant tumors were larger than 5 cm in diameter, to the extraluminal or multi-lumen and extraluminal growth, Enhanced scanning is mostly moderate, significantly enhanced. Conclusion: The CT findings of gastric stromal tumors have certain characteristics, which have important diagnostic value. Atypical cases still need to rely on pathological diagnosis.
