二维和彩色多普勒超声诊断颈部囊性包块及误诊原因分析

本文报告87例颈部囊性包块二维超声和彩色多普勒血流显像(CDFI)情况。并对其在囊实性判断、定位、病因等方面出现错误的原因分析。正确率79.4%(69/87)。错误率20.6%(18/87)。囊实性判断错误主要是将囊肿内浓稠的液体误为实性包块。定位错误主要是对疾病的解剖位置不熟悉。病因错误主要是将腮裂囊肿、海绵状血管瘤、表皮样囊肿中的气体、血栓、纤维组织机化、钙化及炎症误诊为淋巴结结核。认为二维超声结合CDFI有助于提高颈部囊性包块的诊断准确性。

Features and Diagnostic Error Analysis of Cervical Cyst by High Frequency Ultrasonography and Color Doppler Flow Image

In this report,features and diagnostic error were analysised in 87 cases of cervical cyst. The accuracy rate was 79.4% (69/87). The error of determing either solid or cyst was duo to dense liquid. The error of determining the position of the cyst was not familiar with anatomize about cyst. Tuberculous lymphadenitis was misdiagnosed as hyper echogen-ic mass with acoustic shadow casing air or fibresis or calcification or inflammatory focal of branchial cyst and cavernous he-mangioma and epidermoid cyst. Considered that the high frepuency ultrasonograph combine with CDFIwould inscrease the accuracy of cercical cyst.
