16 operatively and histologically proven branchiogenic cysts were evaluated sonographically and the contents of some of them were analysed by microscopy and chemistry. The echographic appearance of all cysts depended on the frequency of the scanheads and ranged from cystic (3.0 MHz) via semi-solid (5.0 MHz) to solid (7.5 MHz). This frequency-related sonographic pattern is caused by the high amount of cholesterin contained in these cysts and permits diagnosis of a branchiogenic cyst.
对16例经手术和组织学证实的鳃裂囊肿进行了超声评估，并对其中一些囊肿的内容物进行了显微镜检查和化学分析。所有囊肿的超声表现取决于扫描探头的频率，范围从囊性（3.0兆赫）经半实性（5.0兆赫）到实性（7.5兆赫）。这种与频率相关的超声模式是由这些囊肿中所含大量胆固醇引起的，有助于鳃裂囊肿的诊断。
