【摘要】：目的探讨甲状腺乳头状癌(PTC)颈部淋巴结清扫术后颈部创伤性神经瘤的声像图特征。方法回顾性分析21例PTC颈部淋巴结清扫术后颈部创伤性神经瘤患者的资料,观察其超声表现,包括病灶的数目、位置、大小、形态、边界、内部回声、是否与神经相连及病灶内血供情况。结果 21例患者共26个病灶中,25个位于颈侧区,1个位于中央区。病灶横径(3.5±1.0)mm,纵径(9.1±2.9)mm。13个病灶呈椭圆形,另13个病灶呈圆形。13个病灶边界清晰,另13个病灶边界模糊。26个病灶均呈不均匀低回声,其中16个病灶内部可见高回声。20个病灶表现为明确与神经相连,余6个病灶与神经相连不明确。20个病灶内可探及少许点状血流信号,余6个病灶内无明显血流信号。超声引导下细针穿刺活检过程中21例患者均主诉针刺部位难以忍受的剧痛,当针尖移开后疼痛消失。结论 PTC颈部淋巴结清扫区域术后低回声病灶,且病灶两端呈现与神经纤维相连的典型声像图特征,同时结合穿刺时患者有剧烈疼痛的主诉,应考虑创伤性神经瘤的可能。
[Abstract]:Objective to investigate the sonographic features of traumatic cervical neuroma after neck lymph node dissection for papillary thyroid carcinoma. Methods 21 cases of traumatic cervical neuroma after PTC neck lymph node dissection were retrospectively analyzed and their ultrasonographic findings were observed. Including the number, location, size, shape, boundary, internal echo, Results of the 26 lesions, 25 were located in the lateral cervical area and 1 in the central area. The transverse diameter of the lesion was 3.5 卤1.0 mm, the longitudinal diameter was 9.1 卤2.9 mm 路13 lesions were oval, the other 13 lesions were round, and the boundary of 13 lesions was clear. In the other 13 lesions, the boundary of the lesions was blurred. All the 26 lesions showed hypoechoic heterogeneity, in which 16 lesions showed hyperechoic, and 20 lesions were clearly connected to the nerve. The remaining 6 lesions were not clearly connected to the nerve. A few punctate blood flow signals could be detected in 20 lesions and no obvious blood flow signals were found in the remaining 6 lesions. 21 patients with fine needle biopsy under the guidance of ultrasound all complained of unbearable severe pain at the acupuncture site. Conclusion the hypoechoic lesions in the PTC neck lymph node dissection area are characterized by typical sonographic features connected with nerve fibers at both ends of the lesion and combined with the main complaint of severe pain during puncture. The possibility of traumatic neuroma should be considered.
