摘　　要：目的探讨周围性神经鞘瘤的声像图特点。方法回顾分析首都医科大学宣武医院2011年3月至2014年11月经手术病理证实的31例周围性神经鞘瘤的超声图像及临床表现。结果31例患者中14例具有触压疼痛等临床症状，17例表现为无痛性浅表肿物。超声表现为低回声结节30例，平均大小（2．9±1．6）cm；包膜完整，边界清，其中1例出现部分囊性变；彩色多普勒超声血流显像：70％（21／30例）病变内无血流信号，30％有少量血流信号（9／30例）；2例为多发病变。另1例术前超声检查显示为无回声，误诊为腱鞘囊肿。结论低回声，包膜完整，边界清，少或无血流信号是超声诊断神经鞘瘤的主要依据，部分病例超声可出现囊性变，少数为多发病变。Objective To investigate the peripheral nerve sheath tumors sonographic features. Methods It was a retrospective analysis of ultrasound images and clinical manifestations which were pathologically confirmed 31 cases of peripheral nerve sheath tumors in March 2011 to November 2014 from Xuanwu Hospital. Results In 14 cases of 31 patients were with a clinical touch and pressure pain, 17 cases showed superficial painless mass. Ultrasound showed hypoechoic nodules 30 cases, with an average size of （2. 9 ± 1.6） cm; encapsulated, border clearance, including 1 case of cystic part; color Doppler flow imaging ultrasound： no intralesional flow signals 21 patients （21/30 patients）, a small amount of blood flow signals 9 cases （9/30 patients） ; 2 cases of multiple lesions. Another one case of preoperative ultrasound examination showed no echo, misdiagnosed as ganglion cyst. Conclusion Hypoechoic encapsulated, border clearance, little or no blood flow is the main basis of ultrasound diagnosis schwannoma, in some cases, there may be cystic ultrasound, a small number of multiple lesions.
