摘要
目的分析视网膜母细胞瘤（RB）在B型超声检查的表现及鉴别诊断价值。方法29例经B型超声、CT及Retcam眼底检查证实为RB患者的36只眼纳入研究。对其超声检查、计算机断层扫描（CT）检查、Retcam眼底检查及其临床资料进行回顾性分析，分析RB的超声特征。结果RB的超声表现大多以眼球后段实质性肿块为特征，呈球形、半球形、不规则形中强回声团块，部分伴有液化坏死腔。25例病人32只眼肿块内有钙化，占病例数的88．9％；3例4只眼肿块中无钙化，占病例数的11．1％，其中1例1只眼初查无钙化，随访过程中出现钙化，占2．8％。CT检查发现24例30只眼内有斑片状、块状及细点状钙化，占病例数的83．3％。经Retcam眼底镜检查可以直接观察到肿瘤的位置及形态，为诊断提供进一步的证据。结论经B型超声检查，可以显示RB的形状、大小、内部特征，对于眼内钙化的发现优于CT扫描及Retcam眼底检查，初查B超无钙化的RB患者，尤其是化疗后有可能出现钙化。B超在RB诊断中有重要应用价值。
Objective To analyze the value of B ultrasonic of the diagnosis of RB （retinoblasto- ma）. Methods The study included 29 cases （36 eyes） of RB examined by B ultrasonic, CT scan and Retcam3. A retrospective study was performed. Results Ultrasound finding of RB showed different solid mass with moderate or strong echo. Partly had the liquefaction and necrosis, 25 cases （32 eyes, 88.9%） had calcification, 3 cases （4 eyes, 11.1%） had no calcification, 1 case （1 eye, 2.8%） among the cases without calcification had chemotherapy and was found the calcification two months later. CT found the calcification in 24 cases （83.3%）. Reteam showed RB directly. Conclusions B ultrasonic can show the characteristic of RB. It is prior to CT and Retcam. If the calcification has not shown at the first examination, it may find the lesion after chemotherapy. So B ultrasonic is im- portant to the diagnosis of RB.
