眼眶肿瘤的高频超声及彩色多普勒诊断

High-frequency ultrasound and color doppler diagnosis of orbital tumors

目的分析探讨眼眶内不同病理性质肿瘤的高频声像及彩色血流的图像特性,以找出一些超声诊断规律。方法回顾分析68例眼眶内肿瘤超声特征、肿瘤好发部位与肿瘤术后病理。结果按病理学组织来源将68例眼眶肿块分为血管源性、神经源性、泪腺、炎性、淋巴瘤、恶性、其它良性肿块等,各组眼眶内肿瘤有多种声像图特征,肿瘤内回声特征与病理结构相关,肿瘤好发部位与病理性质相关;还对各组眼眶肿瘤的彩色血流显示率、血流流速及阻力指数进行了统计学分析处理。结论眼眶内肿瘤的高频声像图与病理学组织类型对比具有一定的特征性超声表现,结合年龄、好发部位及临床表现有助于对病理性质的诊断。

Objective To study the high-frequency ultrasound and color doppler characteristics of different pathological orbital tumors and find out some ultrasonographic diagnostic criteria. Methods The ultrasonographie features and the predilection sites of 68 tumors were retrospectively analyzed and eompared with the results of pathological findings after operation. Results Sixth-eight orbital tumors were classified into different groups according to the pathological morphology, such as vascular-originated tumors, nerve-originated tumors, lacrimal gland, phlegmasia mass, lymphoma, malignancy and others. Ultrasonic imaging characteristics differentiated from each other in the different groups. The internal ulrasonographie features of the orbital tumors were correlated with their pathological morphology. The predilection sites of tumors correlated with their pathological peculiarities. Color flow presentation rates, flow speed and their resistance indexes in each group were also studied and statisticaUy analyzed. Conclusion Compared with the pathological morphology, high-frequency imaging has certain ultrasonographic feature. Combining age, predilection sites and clinical presentations will be great aids to the pathological nature diagnosis of the tumors.
