CT Diagnosis of Brachial Cleft Cyst and Fistula / 中国医学影像技术

ABSTRACT

Objective　 To improve the recognization and the diagnostic accuracy of brachial cleft cyst (BCC) by CT scan. Methods 　CT findings of 10 BCC proved surgically and pathologically were retrospectively reviewed. Results　 BCC，CT number 22～33 Hu；with the enhanced wall and the non-enhanced cystic part. If infections exist，the margin would be obscure and the internal density be increased. These cysts commonly located in the anterior triangle area of the neck or along the anterior border of the sternocleidomastoid muscle. The first brachial cleft fistula was not displayed. Conclusion　 CT scan can not only clearly show the location，enhanced characters and the relationship to the adjacent tissues of the BCC，but also can be possible to make the diagnosis of the BCC，but not the brachial cleft fistula.
