皮肤分叶状毛细血管瘤的超声表现

Ultrasound findings of skin lobulated capillary hemangioma

目的探讨皮肤分叶状毛细血管瘤的特征性超声表现。方法回顾性分析4例生长于皮肤经手术病理证实为分叶状毛细血管瘤的声像图表现,包括病变的位置、大小、形状、回声、边界、是否存在钙化和声晕,以及彩色多普勒血流分布特点。结果 4例分叶状毛细血管瘤患者中,头部2例,背部1例,腹部1例;3例隆起性生长,1例向下生长达皮下脂肪层。与脂肪层回声对照,其中1例为等回声,3例为低回声。病灶均呈椭圆形,边界清晰,内部回声均匀,内部无钙化灶,周边无声晕。4例病变内部彩色血流信号丰富,其中2例血流信号充满整个病灶,4例病变均见一支较粗大供血血管进入肿块内,脉冲多普勒呈低阻动脉血流频谱。结论高分辨率超声可以清晰显示皮肤分叶状毛细血管瘤的位置、形态及血流特征,对协助临床诊断及决策治疗方案有重要价值。

Objective The purpose of this study was to describe the ultrasound findings of pathologically confirmed lobular capillary hemangioma of the skin in four patients.Methods Retrospective analysis of 4 cases of ultrasound findings of lobulated capillary hemangioma confirmed by surgery and pathology,including:location,size,shape,echo,boundary,presence of calcification,and color Doppler flow characteristics.Results The study group were admitted with a nodule or a protruding nodule in the skin.Among the 4 patients,2 cases were in the head,1 in the back and 1 in the abdomen.3 cases showed bulging growth,and 1 case grew deep into the subcutaneous fat layer.The fat layer echo was used as a control,one of which was an echo and three of which were hypoechoic.The lesions were all elliptical,with clear boundaries,uniform internal echo,no calcification inside,and no hypoechoic rim.Color Doppler sonography showed marked internal vascularity in two cases and profuse blood flow throughout the nodules in two cases.Color Doppler sonography demonstrated a feeder vessel and pulsed wave Doppler showed internal low-resistance arterial waveform in all the cases.Conclusion High-resolution ultrasonography can clearly show the location,morphology and blood flow characteristics of skin lobulated capillary hemangioma,,which is of great value in assisting clinical diagnosis and developing treatment plan.
