摘要
目的:探讨彩色多普勒超声对胃肠道及胃肠道外恶性间质瘤肝转移的诊断价值。方法:回顾并分析2015年1月—2020年1月解放军联勤保障部队第九〇四医院收治的经病理学及免疫组织化学证实的17例胃肠道恶性间质瘤及3例胃肠道外恶性间质瘤伴肝转移患者的临床资料,分析恶性间质瘤原发灶及肝内转移灶超声图像特征。结果:17例胃肠道恶性间质瘤原发灶24个,肝内转移灶31个;3例胃肠道外恶性间质瘤原发灶7个,肝内转移灶9个。原发灶及肝内转移灶均可表现为实性、囊实性,囊实性病灶占比83.1%。其中大部分原发灶(61.3%)表现为局部边缘模糊,部分原发灶(41.9%)形态不规则,呈浅分叶状;肝内转移灶更多地呈现为边界清晰(77.5%)、形态规则(82.5%)。结论:与恶性间质瘤原发灶相比较,形态规则、边界清晰的囊实性占位性病变为肝内转移灶的典型特征,该特征表现对判断恶性间质瘤肝内转移灶具有较大临床意义。
Objective:To investigate the value of color doppler ultrasound in the diagnosis of liver metastasis of gastrointestinal and extragastrointestinal malignant stromal tumors.Methods:The clinical data of 17 cases of gastrointestinal malignant stromal tumor and 3 cases of extragastrointestinal malignant stromal tumor with liver metastasis confirmed by pathology and immunohistochemistry from January 2015 to January 2020 in 904th Hospital of the Joint Service Support Force of the PLA were analyzed retrospectively,and the ultrasonic image characteristics of the primary and intrahepatic metastasis of malignant stromal tumors were analyzed.Results:There were 24 primary tumors and 31 intrahepatic metastases in 17 cases,7 primary tumors and 9 intrahepatic metastases in 3 cases.Both primary lesions and intrahepatic metastases showed solid and cystic solid lesions,accounting for 83.1%.Most of the primary lesions(61.3%)showed blurred local edges,and some(41.9%)showed irregular morphology and shallow lobulation.Intrahepatic metastases showed clear boundaries(77.5%)and regular morphology(82.5%).Conclusion:Compared with the primary tumor of malignant stromal tumor,the cystic solid space with regular shape and clear boundary was the typical feature of the metastasis,it is of great clinical significance to judge the intrahepatic metastasis of stromal tumors.
