摘要
目的探讨彩色多普勒超声在眼内肿瘤诊断和鉴别诊断中的价值。方法用高频探头彩色多普勒超声对273例(301只眼)眼内肿瘤患者进行检查,观察肿瘤的二维图像和血流特征。结果153例(178只眼)视网膜母细胞瘤患者中,138例(149只眼)彩色多普勒超声可显示肿瘤内的点状或块状的强回声钙化斑,152例(177只眼)可显示肿瘤内呈枝状的供血血流分布;4例Coats病、2例永存性原始玻璃体增殖症和3例(6只眼)未成熟儿视网膜病变患者血流特征显示为脱离的视网膜上或与视盘相延续的条状血流。66例脉络膜黑色素瘤、4例睫状体黑色素瘤侵犯周边脉络膜以及19例脉络膜转移癌患者中的15例彩色多普勒超声发现肿瘤内有丰富的树枝状供血血管血流分布,12例脉络膜血管瘤显示肿瘤内呈团状或斑点状的混杂血流分布,2例睫状体髓上皮瘤和8例脉络膜或视网膜下积血病变内无血流显示。结论利用彩色多普勒超声结合脉冲多普勒对肿瘤内血管血流特征的分析有助于对眼内肿瘤的诊断和鉴别诊断。
Objective To evaluate color Doppler ultrasonography （CDU） in the diagnosis of intraocular tumor. Methods Two hundred seventy-three cases（301 eye） of intraocular space-occupying lesions were examinated by high-resolution CDU to observe the two-dimensional gray-scale image and vasculature of intraocular tumors. Results Intratumor calcifying spot could be detected in 138 cases（149 eye） of 153 cases（178 eye） with retinoblastoma,and intratumor blood flow with branchy pattern could be found in 152（177 eye） of 153 cases（178 eye） with retinoblastoma. In 4 Coats disease and 2 persistent hyperplastic primary vitreous and 3 retinopathy of prematurity, intratumor calcifying spot couldn＇t be detected,and the band blood flow of the detached retinal vessels could be detected. Intratumor blood flow with branchy pattern could be detected in all 66 choroidal melanomas and 4 melanomas of ciliary body with infiltrated choroid and 15 of 19 choroidal metastases. Intratumor blood flow with ＂simulating vessel pool＂ or conglomerate sparkled pattern could be found in 12 choroidal hemangioma. No intrinsic flow was detected in 8 choroidal hemorrhages or subretinal hemorrhages and 2 teratoid medulloepitheliomas. Conclusions CDU is of significance in the diagnosis and differention of intraocular tumors.
