目的：本文总结44例眼眶神经鞘瘤病理分型与其B超和CDI影像学表现,分析其不同分型中囊性变和血管分布量与其在超声和CDI影像表现是否存在一定关系。 　　方法：回顾2001-01/2008-12眼眶神经鞘瘤44例的病理和B超检查,42例CDI检查,分析各型病理含囊变例数,含血管例数及各型间比较；分析超声回声不均匀与病理所见囊变,和CDI血流情况与病理所见血管的相关性。结果：各型间比较神经鞘瘤含有囊结构为Antoni A型中较多,混合型次之, Antoni B型最少,有统计学意义( P<0.05)。含较大血管结构是Antoni B型比例最高,混合型次之,Antoni A型第三,但是缺乏统计学意义。超声显示内回声不均匀与病理见囊病的符合率为50.0%,内回声均匀,未见囊变的符合率为69.3%。 CDI检查B型肿瘤查到血流信号占83.0%,A型占59.2%,两者之间无统计学意义。 CDI 显示较多的血流信号与病理符合率100%,有显著性差异。 　　结论：眼眶神经鞘瘤多为A型和B型结构混合存在,以A型为主较多见,病理特征除细胞学特点外,A型区多见囊变。 B型区血管多见。超声波检查内回声的改变能准确反应组织结构,其内回声的不均质性,与肿瘤内囊变区相符。 CDI血流信号能准确反映肿瘤内血管分布。

AIM:To summarize the pathology, B-scan ultrasound and CDI manifest of orbital neurinoma. Try to analyze the connection between the different amounts of cystic degeneration and vascular distribution and the findings in ultrasound and CDI imaging. METHODS:A retrospective analysis was performed on 44 cases with orbital neurinoma treated during January 2001 to December 2008, including 44 cases of pathological sections and B-scan ultrasound pictures, and 42 cases of CDI pictures. The connection between them were compared. RESULTS: The incidence of cystic changes in Antoni type A was the highest, mixed type followed, Antoni type B at least, which was statistical significance ( P<0.05). Antoni type B had more blood vessel structures, mixed type followed, Antoni type A at least, which was not statistical significance. The coincidence rate between the cystic changes and nonuniform echo in ultrosonography was 50. 0%. On the other hand, between the non-cystic changes and uniform echo, the coincidence rate was 69. 3%. On CDI, 83. 0% of Antoni type B and 59. 2% of Antoni type A can be detected blood current with no statistical significance. CDI showed compliance rate of 100% between blood flow and pathology, with statistical significance. CONCLUSION:Mixed type is the most common type in orbital neurinoma. Cystic changes are more common in Antoni type A, while blood vessel structures are more common in Antoni type B. Ultrasonography can demonstrate the site, configuration and characteristics of the tumors, which is coincidence with the cystic changes and the blood vessels.
