软组织神经鞘瘤的超声诊断

Ultrasonographic diagnosis of neurilemmoma in soft tissue

目的探讨高频超声对软组织神经鞘瘤的诊断价值。方法回顾性分析20例经手术病理证实的软组织神经鞘瘤的声像图表现。结果软组织神经鞘瘤为实性类圆形肿物,边界清,有完整包膜,内部呈低回声,部分有囊性变,部分可见肿物与神经纤维相连。CDFI示血流分级0级～1级为主。结论高频超声声像图特征结合临床病史能够比较准确地对软组织神经鞘瘤作出诊断,如果发现有神经纤维与肿物相连,对于定性诊断将有十分重要的意义。

Objective To explore the value of ultrasonography in the diagnosis of neurilemmoma in soft tissue.Methods Twenty patients with surgically and pathologically proved neurilemmoma in soft tissue underwent ultrasonographic examinations and their ultrasonographic features were analyzed retrospectively.Results Neurilemmoma arising from soft tissue was found to be round or elliptic solid mass lesion with well defined margin and complete capsule,inner uniform hypoecho and partially complicated with cystic change.In part cases,the lesion was found to be in a direct continuity with cord- like echogenic structure consistent with a nerve by echography.Color Dopler flow imaging(CDFI) showed that the blood flow in the lesions was mostly grade 0～ 1.Conclusion The integration of high frequence ultrasonography and clinically medical history can make a definite diagnosis for neurilemmoma in soft tissue.When the nerves connect the masses the diagnosis of neurilemmoma in soft tissue shall be suggested.
