【摘要】：目的探討甲狀腺乳頭狀癌(PTC)頸部淋巴結(jié)清掃術(shù)后頸部創(chuàng)傷性神經(jīng)瘤的聲像圖特征。方法回顧性分析21例PTC頸部淋巴結(jié)清掃術(shù)后頸部創(chuàng)傷性神經(jīng)瘤患者的資料,觀察其超聲表現(xiàn),包括病灶的數(shù)目、位置、大小、形態(tài)、邊界、內(nèi)部回聲、是否與神經(jīng)相連及病灶內(nèi)血供情況。結(jié)果 21例患者共26個病灶中,25個位于頸側(cè)區(qū),1個位于中央?yún)^(qū)。病灶橫徑(3.5±1.0)mm,縱徑(9.1±2.9)mm。13個病灶呈橢圓形,另13個病灶呈圓形。13個病灶邊界清晰,另13個病灶邊界模糊。26個病灶均呈不均勻低回聲,其中16個病灶內(nèi)部可見高回聲。20個病灶表現(xiàn)為明確與神經(jīng)相連,余6個病灶與神經(jīng)相連不明確。20個病灶內(nèi)可探及少許點狀血流信號,余6個病灶內(nèi)無明顯血流信號。超聲引導(dǎo)下細針穿刺活檢過程中21例患者均主訴針刺部位難以忍受的劇痛,當針尖移開后疼痛消失。結(jié)論 PTC頸部淋巴結(jié)清掃區(qū)域術(shù)后低回聲病灶,且病灶兩端呈現(xiàn)與神經(jīng)纖維相連的典型聲像圖特征,同時結(jié)合穿刺時患者有劇烈疼痛的主訴,應(yīng)考慮創(chuàng)傷性神經(jīng)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 鹵1.0 mm, the longitudinal diameter was 9.1 鹵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.
