超声检查对颈部神经源肿瘤的诊断价值

目的 探讨并总结超声检查对颈部神经源肿瘤的价值，进一步提高诊断准确性。方法 对48例患者行手术前超声检查，并与穿刺细胞学及术后病理结果进行对照分析。结果 47例良性颈部神经源肿瘤均为圆形或椭圆形肿物，边界清楚，内部回声均匀，其中多伴囊变61．7％（29／47），其囊变形态也有一定特点；另1例神经源肿瘤恶变，表现为肿物较大，边界不清，内部回声不均匀。彩超显示大部分病变血流较丰富，属Ⅱ～Ⅲ级，共计39例，检测部分病灶内血流情况发现有一定的特点。结论 总结分析超声图像特点，注重颈部神经源肿瘤的诊断及鉴别诊断，其诊断正确率可达85％，术前超声检查对诊断颈部神经源肿瘤很有价值。

Ultrasonographic Diagnostic Neurogenic Tumors in the Neuroma of the Neck

Objective To further improve the sonographic diagnostic accuracy, we summarize the value of ultrasound for the neuroma of the neck. Methods A retrospective analysis was performed on 48 cases with the neuroma of the neck. The results of preoperative ultrasonographic examination were compared with that of preoperative cytology and postoperative pathology. Results Of 48 neurogenic tumors in the neck, 47 were benign, its shape round or ellipse, its border clear, and inner echo uniform, the rate of cyst was 61.7%(29/47),the morphology of the cyst is the unique. The another one was malignant, the volume was bigger than that of the benigns, its border not clear, inner echo not uniform. Most of the tumors have the rich blood supply in colour Doppler sonography, 39 cases belong to II~III grade, and the blood supply is the unique. Conclusion The diagnostic accurate rate is 85% for neuroma of the neck by ultrasound, preoperative sonographic examination is considered to be very significance in the diagnosis of the neuroma in the neck.
