浅表器官表皮样囊肿的超声表现及分型

目的:探讨浅表器官表皮样囊肿的超声声像图特征。方法:对41例浅表器管表皮样囊肿的声像图进行回顾性分析,总结声像图特征对其进行分型,并与病史及病理结果相对照。结果:肿块多位于皮下,边界清晰,有包膜,呈椭圆形,无1例肿块内部呈典型囊肿无回声暗区,均充满光点,根据肿块内部声像图表现分为均匀细弱光点型11例(11/41,27%),均匀光点夹杂小暗区或暗带型5例(5/41,12%),均匀光点夹杂短线状光带型8例(8/41,20%),不均匀型13例(13/41,32%),"洋葱征"型4例(4/41,10%)。结论:表皮样囊肿具有特征性声像图表现,其分型与病理基础相关,超声在表皮样囊肿的诊断中具有重要作用。

Characteristics and Classification of Superficial Epidermoid cysts

Objective：To investigate the characteristics and classification of Superficial Epidermoid cysts on ultrasonography. Methods：The ultrasound findings of 41 superficial epidermoid cysts were retrospectively reviewed, comparing with clinical and pathological features.Results：According to various echogenicity features ,The appearance of superficial epidermoid cysts ultrasonography were classified into five types： homogeneous echogenicity type （11/41,27%）;homogeneous echogenieity with little anechonic areas type（5/41, 12%）;homogeneous echogenicity with short aeuostic lines type（8/41,20%）;inhomogeneous echogenicity type （13/41,32%）; onion-like eehogenicity type （4/41, 10%）.Conclusion：The ultrasonic images of superficial epidermoid cysts have certain characters,The ultrasonic patterns associated with its pathological features. Ultrasotmd plays an important role in diagnosis of superficial epidermoid cysts.
