目的:探讨鼻咽癌肝内转移灶的声像图特征及超声显像在鼻咽癌肝转移诊断中的临床作用。方法:回顾性分析103例经病理确诊的鼻咽癌肝转移患者,首先应用二维超声常规检查了解病灶的位置、大小及声像图特点,然后以彩色多普勒显示病灶内及周围的血流形态及其分布情况。结果:肝内出现病灶时为散在的多个大小不等的“牛眼征”样光团,随着病情的发展及病灶的增大,肿块中央坏死液化呈“囊肿型”,后方回声有增强效应,彩色多普勒显示部分肿块内无彩色血流信号,部分肿块周边可见门静脉血流信号;部分肿块厚壁囊腔内乳头状突起处可探及动脉血流信号。结论:超声监测鼻咽癌肝转移简便、经济,可重复性对鼻咽癌的疗效监测有很大的实用价值,应为首选的影像检查方法。
Objective: To investigate the ultrasonographic features of intrahepatic metastases of nasopharyngeal carcinoma and its clinical significance in the diagnosis of liver metastases of nasopharyngeal carcinoma. Methods: A retrospective analysis of 103 cases of pathologically confirmed liver metastases of patients with nasopharyngeal carcinoma, the first application of two-dimensional ultrasound routine examination to understand the location of lesions, size and sonographic features, and then color Doppler display of blood within and around the lesion Flow patterns and their distribution. Results: In the liver, a number of scattered “Bovine Eye” light samples were scattered in the liver. As the disease progressed and the lesions increased, the central necrosis liquefaction showed “cyst type” and the posterior echo was enhanced Effect, color Doppler showed no intracranial blood flow within the mass signal, some of the visible peripheral blood flow of the portal vein signal; part of the thick cystic cavity papillary bursa and arterial blood flow signal can be detected. Conclusion: Ultrasound monitoring of liver metastasis of nasopharyngeal carcinoma is simple, economical and reproducible. It has great practical value for the curative effect monitoring of nasopharyngeal carcinoma and should be the first choice of imaging method.
