摘要
目的探讨彩色多普勒超声(CDI)技术在儿童眼眶肿瘤诊断中的临床价值。方法应用CDI技术对39例儿童眼眶肿瘤患者肿瘤内部回声及彩色血流显像进行检测。结果在39例儿童眼眶肿瘤中,毛细血管瘤8例,横纹肌肉瘤2例,瘤体内CDI均可检测出丰富的动脉血流信号;皮样囊肿12例,淋巴管瘤8例,瘤体内CDI检测均无血流信号;静脉性血管瘤6例中,CDI检测出静脉血流信号3例;3例静脉曲张在颈静脉加压和压力解除过程中示动态血流变。结论CDI技术在儿童眼眶肿瘤的鉴别诊断中有重要的临床价值,联合判断肿瘤特征性内部回声及声像图有助于对肿瘤进行定性诊断。
Objective hnageology diagnosis of orbital tumor is very critical for the determination of nature of tumor in childhood patients. It is very necessary to comprehensively assess the results of clinical manifestations and imageology for the identification of orbital tumor. This study was to evaluate the clinical value of ultrasonography and color Doppler imaging （CDI） in the diagnosis of orbital tumors in children. Methods The clinical data,B-type echograms and CDI of 39 children with orbital tumors including capillary hemangioma, lymphangioma, venous hemangioma, rhabdomyosarcoma, dermoid cyst, varicosity etc. were analyzed retrospectively. Results Among 39 cases of orbital tumors in children,8 cases of capillary hemangioma and 2 cases of rhabdomyosarcoma showed the signals of artery blood flow from CDI ultrasound examination. No blood flow signal was obtained in 12 cases with dermoid and 8 cases with lymphangioma. The venous blood flow signals were examined from CDI examination in 3 out of 6 cases of venous hemangioma. Dynamic blood flow changes were seen from CDI in 3 cases with varicosis. Conclusion Combination of B-type ultrasonography and CDI is useful for the diagnosis of orbital tumors in childhood patients.
