浅表组织表皮样囊肿的声像图分析

目的分析全身浅表组织表皮样囊肿的声像图特点。方法回顾性分析36例浅表器官表皮样囊肿的患者临床资料,对其形态、大小、位置、内部回声、边界、包膜、后方回声、有无感染及血流情况进行分析。结果 36例中肿块位置均位于皮下,有包膜,边界清,内部回声不均,成细密点状回声,后方回声略增强,肿物内部无血流信号。病理结果显示肿物切面为囊性,壁较薄,囊内表面光滑,囊内为灰白色豆渣样物。结论表皮样囊肿声像图具有一定特征性,高频超声具有较高的诊断价值。

The Analysis on Ultrasound Images of Epidermoid Cyst in Superficial Tissues

Objectives to analyze the features of ultrasound images of epidermoid cyst in superficial tissues.Methods The ultrasound images were retrospectively discussed in the 36 patients with epidermoid cyst according to the clinical materials,the shape,the size,the site,the interior echo types,the border,the envelope,the posterior echo types,infection accompanied and the blood flow signals.Results In 36 cases,lumps were detected in the superficial tissues.We can find envelops,clear border,uneven internal echoes,thin and dense spotty echoes,a little enhanced posterior echoes and so on.No signals in the interior lumps.The pathological results show that cystic section lump is thin and smooth in the inner wall.The contents in the cysts are like bean dregs.Conclusions The ultrasound images of epidermoid cysts have certain characteristic.High frequency ultrasound has high diagnosis value.
