摘　　要：目的:总结分析儿童毛母质瘤的超声声像图表现,探讨超声诊断价值。方法:回顾性分析本院4年间经小儿外科手术病理证实的73例共75个毛母质瘤的临床及超声检查资料,评估病变的大小、边界、形态、内部回声、钙化、在皮肤上的位置及血流情况。结果:儿童毛母质瘤病灶多为单发(97.3%,71/73)。好发于脸颊(22.7%)和颈部(21.3%),高频超声显示病灶多数位于真皮与皮下脂肪交界处(94.7%,71/75)、形态规则呈圆形或椭圆形(90.7%,68/75)、大多数儿童毛母质瘤为实性回声(97.3%,73/75),内部回声不均,可见高低回声混合、多数结节内部伴有钙化者(82.7%,62/75),约半数结节边缘呈低回声声晕改变(48.0%,36/75)。结论:结节内回声不均匀伴钙化和结节边缘呈低回声声晕是儿童毛母质瘤的特征性超声表现,熟悉其超声表现有助于提高超声诊断符合率。Objective:To analyze the ultrasonographic features of children pilomatoma and to investigate the diagnostic value of ultrasound.Methods:We retrospectively reviewed the ultrasound scans of pathologically proven pilomatricomas with 75 PM in 73 children and performed over a period of 4 years.We evaluated images for the size of the lesion,borders,morphology,content,calcification,location on the skin and colour Doppler characteristic.Results:Most of the lesions in children with trichommatoma were single(97.3%,71/73).Most lesions occurred in cheek(22.7%)and neck(21.3%).High-frequency ultrasound showed that the lesions were mostly located at the junction of dermis and subcutaneous fat(94.7%,71/75),the shape was round or oval(90.7%,68/75),and most children’s PM was solid echo and mixed echo(97.3%,73/75).internal echo of most PM was uneven,and mixed with high and low echo,and(82.7%,62/75)were accompanied by calcification,and about half of the PM were accompanied by low echo halos changes in(48.0%,36/75).Conclusion:We showed that the calcification and hypoechoic rim are the characteristic ultrasonic findings of children PM,and familiarity with the ultrasonic findings is helpful to improve the diagnostic coincidence rate.
