背景资料：创伤性神经瘤很容易与颈部复发性淋巴结病混淆，导致患者焦虑，需要细针穿刺（FNA），甚至手术。本研究的目的是评估超声（US）特征，以区分创伤性神经瘤和颈外侧淋巴结清扫术（LND）后复发性淋巴结病，重点是与受累神经的直接连续性。本研究比较了36例连续患者的56个创伤性神经瘤的超声特征，在34例有甲状腺癌全切除术和LND病史的连续患者中，有56例复发性淋巴结病。结果：LND后外伤性神经瘤的超声检出率为17.8%（36/202），LND后的神经瘤的超声检出率为17.8%（36/202），LND后的神经瘤的超声检出率为17.8%（36/202）。98.2%（55/56）的创伤性神经瘤与受累神经直接相连。其中终末型（4/55，7.3%）和梭形（51/55，92.7%）神经瘤均受累。两组的短径、短长径比、位置、形态、边界、回声强度等均有显著性差异（p < 0.001）。没有创伤性神经瘤有一个门线，血管流，或囊性portion.Conclusions：直接连续性与颈丛可能是一个特征性的创伤性神经瘤LND后的US功能。这一特点，沿着辅助发现，可以防止不必要的手术以及痛苦的FNA。
Background: Traumatic neuroma may be easily confused with recurrent lymphadenopathy in the neck, causing patient anxiety, need for fine-needle aspiration (FNA), and even surgery. The purpose of this study was to evaluate the ultrasound (US) features that differentiate traumatic neuroma from recurrent lymphadenopathy after lateral neck dissection (LND), focusing on direct continuity with the involved nerve.Methods: This study compared US features of 56 traumatic neuromas in 36 consecutive patients, with 56 recurrent lymphadenopathies in 34 consecutive patients who had a previous history of total thyroidectomy and LND for thyroid cancer. Direct continuity of a nerve with a nodule and other US factors of a nodule (the short axis diameter, short-to-long axis ratio, location, shape, margin, echogenicity, vascular flow, hilar line, cystic portion, and echogenic dots) were evaluated in the two groups.Results: Traumatic neuromas after LND had a prevalence of 17.8% (36/202) on US. Direct continuity with the involved nerve was visible in 98.2% (55/56) of the traumatic neuromas. The involved nerves in these traumatic neuromas were either terminal type (4/55, 7.3%) or spindle type (51/55, 92.7%). The short axis diameters, short-to-long axis ratio, location, shape, margin, and echogenicity were significantly different (p < 0.001) in these two groups. None of the traumatic neuromas had a hilar line, vascular flow, or cystic portion.Conclusions: Direct continuity with the cervical plexus may be a characteristic US feature of traumatic neuroma after LND. This feature, along with ancillary findings, may prevent unnecessary surgery as well as painful FNA.
