摘要
目的:探讨A/B型超声检查在脉络膜血管瘤和脉络膜黑色瘤诊断中的作用。方法:对经眼科A/B超声检查及眼底荧光血管造影、CT、MRI等检查,诊断为脉络膜血管瘤和脉络膜黑色素瘤8眼的眼底表现及A/B型超声检查中的形态学表现进行分析。结果:脉络膜血管瘤5例均为孤立性,声像特征为后极部及视乳头附近球壁局限性卵圆形或盘状隆起,凸向玻璃体,表面光滑,内回声均匀,中等强度,无声影,可探及球后壁。脉络膜黑色素瘤声像特征眼内半圆形或蘑菇形实性隆起物,边界清楚、肿物前缘光滑锐利,光点密集明亮、向后逐渐减弱,接近眼球壁出现无回声区、局部眼球壁较周围正常低下即“挖空征”。结论:应用A/B型超声对脉络膜血管瘤和脉络膜黑色素瘤做出临床诊断,对难以确诊的病例,通过眼底荧光血管造影、CT、MRI等影像学可帮助诊断。
Objective： To investigate the effect of A/B ultrasonography on diagnosing chorioidal hemangioma and melanoma.Methods： 8 eyes of choroidal hemangioma and melanoma performed A/B ultrasonography, fluuorescenee fundus angiography （FFA）, CT and MRI examinations.The A/B ultrasonic features were analyzed.Results： 5 choroidal hemangioma were isolated.The imaging features included ovate or disk shaped prominence into vitreous space localized near posterior pole or discus opticus, smooth surface, uniform echo in moderate intensity which may reached posterior ocular wall. The imaging of choroidal melanoma showed intraocular hemicycle or mushroom shaped solid prominence with clear edge. The anteior border of echo was sharp with much bright spot, then decreased backward, The echo disappeared near the ocular wall and showed ＂empty sign＂. Conclusion ：A/B ultrasound provides evidence in diagnosis in choroidal hemangioma and melanoma. FFA, CT and MRI is helpful for diagnosing in undefinite case.
