三维超声在脉络膜黑色素瘤诊断中的应用

Value of three-dimensional ultrasound in diagnosis of choroidal melanoma

目的探讨三维超声在脉络膜黑色素瘤诊断中的应用价值。方法应用OTI3D-iscan超声系统,对20例20只眼病理诊断脉络膜黑色素瘤病例的三维超声作回顾性分析。在静态下对图像进行多层面切割和方位旋转,以全面观察肿瘤形态和生物测量。结果本组20例脉络膜黑色素瘤病例的三维超声成像诊断依据为形态、脉络膜凹陷、视网膜脱离、CTH色彩改变、挖空现象等。其中18例诊断为脉络膜黑色素瘤,临床符合率达90%。结论三维超声对脉络膜黑色素瘤的诊断以及对肿瘤生物测量、肿瘤形态的观察具有重要价值。

Objective To evaluate the value of three-dimensional （3D） ultrasonic examination in diagnosis of choroidal melanoma. Methods Twenty eyes （20 cases） proved as choroidal melanoma pathologically were reviewed retrospectively with their 3D ultrasonic examinations （OTI, Canada） preoperatively. Rotating cut method in static stage was used to observe and measure the tumor. Results In 3D ultrasonic examination, 18 cases were diagnosed as choroidal melanoma according to tumor shape, choroidal depression, retinal detachment, CTH color change and cavernous phenomena of choroidal melanoma. The consistent rate of 3D ultrasonic examination and pathology was 90%. Conclusions 3D ultrasonic examination was valuable for diagnosis of choroidal melanoma, especially in observing and measuring the tumor.
