Abstract |
Objectives :The purpose of this study was to evaluate the variable sonographic features in addition to clas-sic findings and to find the helpful characteristic findings for diagnosis of branchial cleft cysts.
Subjects and Methods :We retrospectively analyzed the sonographic finding of 16 histopathologically proven branchial cleft cysts. Assessment involved the following variables : location related to carotid artery, size, cyst wall, border, margin, shape, internal echotexture, post echoic enhancement, orientation of longitudinal axis rel-ative to the long axis of the neck, and tapering edge.
Results :Most branchial cleft cysts were seen as well defined(15/16), oval shape(13/16), smooth inner (12/16) and outer margin(13/16), and post echoic enhancement(16/16). Their diameter varied from 1 to 6cm (mean 3.3cm). The branchial cleft cysts showed variable internal echopatterns;hyperechogenicity or pseu-dosolid appearance(1/16), heterogeneous echogenicity(4/16) in addition to classic form of anechoic(5/16) or hypoechoic internal echogenicity(6/16). Longitudinal axis of most branchial cleft cysts were arranged in the direction of the long axis of the neck(13/16) and some branchial cleft cysts had tapering edge(6/16).
Conclusion :If both atypical sonographic findings and location are showed, longitudinal arrangement of long axis and tapering edge of branchial cleft cysts are helpful findings for differential diagnosis. |
