摘要：

目的:分析胃肠道外间质瘤(EGIST)的超声图像特点,评价超声检查的临床应用价值。方法:收集15例经病理证实为EGIST患者的临床和超声资料进行回顾性分析,总结超声图像特点,其中术后10例进行6~48个月超声随访。结果:15例EGIST均单发,来源于肠系膜6例、网膜4例、腹膜后4例、肛周1例;肿瘤最大径约23.3 cm,平均(9.3±2.2)cm;7例EGIST呈类圆形,5例呈分叶状,3例呈不规则形;11例瘤体内见液化坏死区,呈囊实混合性回声,4例呈实性回声;12例瘤体内血流丰富,2例血流稀少,1例无血流显示。超声随访显示:6例病情进展,4例病情稳定。结论:超声检查对EGIST的诊断和随访具有重要临床应用价值。

Objective: To estimate the clinical value of ultrasound examnination by analyzing the features of ultrasonic images of extragastrointestinal stromal tumors(EGIST). Methods: Clinical and ultrasonic data of fifteen cases with EGIST confirmed through pathology were analyzed retrospectively, and the ultrasonic features were generalized.10 patients after the surgery were followed up with ultrasound for 6 to 48 months. Results: All of the 15 cases with EGIST were solitary with 6 cases from mesentery,4 from omenta,4 from retroperitoneal space and 1 from crissum.The maximum diameter of tumors was 23.3 cm; the mean was (9.3±2.2)cm. 7 cases were similar round-shaped,5 lobulated and 3 irregular. Eleven tumors had liquefaction necrosis areas and showed mixed cystic and solid echo,four cases showed solid echo.There were rich blood flow signals in twelve cases, scarce in two cases and none in one case.Ultrasonic follow-up displayed that the state of six cases was progressing and the state of four cases was stable. Conclusion: Ultrasound imaging examination is highly helpful for diagnosis and follow-up of EGIST.
