摘要
目的 观察节细胞神经瘤(GN)超声表现。方法 回顾性分析18例接受超声检查的GN患者,均为单发病变,观察其超声表现。结果 18个GN最大径0.9~19.0 cm、中位最大径5.6(3.4,8.8)cm,边界均清晰,对周围脏器和血管无侵犯。13个GN病灶呈纵向生长、5个呈横向生长;11个形态不规则、质地较软,沿周围组织间隙蔓延式生长,推移而不侵犯周围组织结构,7个呈类圆形膨胀性生长。18个内部均为较均匀的实性低回声,8个瘤体内可见散在、斑块样/蛋壳样钙化灶,5个肿瘤内部和/或周边探及少许短线样血流信号。结论 GN超声表现为实性低回声包块,边界清晰,可呈膨胀性生长的类圆形或沿周围组织间隙蔓延生长的不规则形,内部可见散在钙化灶,多无明显血流信号或仅见少量血流信号。
Objective To observe the ultrasonic manifestations of ganglioneuroma(GN).Methods Totally 18 patients with single GN lesion who underwent ultrasonic examinations were enrolled,and the ultrasonic manifestations were retrospectively observed.Results The maximum diameter of 18 GN lesions was 0.9—19.0 cm,and the median maximum diameter was 5.6(3.4,8.8)cm,all with clear boundaries and no invasion of surrounding organs nor blood vessels.Among 18 lesions,longitudinal growth was noticed in 13,while lateral was observed in 5 lesions,11 were found with irregular morphology and soft texture spread along the gaps of surrounding tissue,not invasived but compressed the surrounding structure,7 with quasi circular and expansive growth.All 18 lesions showed relatively uniform solid hypoechoic,includuing 8 with scattered,plaque like/eggshell like calcifications,5 with small amount of short linear blood flow signals inside and/or around.Conclusion Ultrasonic manifeatations of GN included solid hypoechoic mass with clear boundary,presented as quasi circular shape with expansive growth or irregular shape that spread along the gaps of surrounding tissue,might be found with scattered calcifications inside,mostly without obvious blood flow signals or only a small amount of blood flow signals.
