Objective:This study evaluated two-dimensional and three-dimensional ultrasound (US) features of congenital Hemangioma (CH), and to compare it with infantile hemangioma (IH).Methods:Between December 2015 and January 2019, ultrasound examination of IH and CH cases were carried out in the Ninth People’s Hospital Affiliated to Medical School of Shanghai Jiao Tong University. US findings were retrospectively evaluated. On US images, the size, depth, echotexture, echogenicity, margin, vessel density, blood flow velocity and 3-dimension ultrasound pattern were recorded. Students’ t, variance analysis, K-W test and χ2 test were used for comparison. Results:A total of 93 CH cases and 94 IH ones were included in the study. There were 59 males and 34 females aged from 5 days to 3 years. Among 93 CH cases, 30 cases were rapid involuting congenital hemangioma (RICH), 42 cases were non involuting congenital hemangioma (NICH), and 21 cases were partial involuting congenital hemangioma (PICH). There were 98 lesions in 94 patients with IH, including 22 males and 72 females, aged from 1 month to 1 year.The maximum diameter and depth of CH was (4.12±2.36) cm and (1.02±0.61) cm respectively, the lesions were mixed echoic with hypo-echo and many visible vessels mainly with well-defined, sometimes calcification. The maximum diameter and depth of IH was (2.54±1.21) cm and (0.85±0.47) cm respectively, the lesions were mixed echoic with hyper-and hypo-echo, and hypoechoic mainly with well-defined. The vascular density of IH and CH was (5.32±1.40)/cm 2 and (6.01±1.10)/cm 2( t=-3.794, P<0.001)respectively with low arterial peak systolic velocity and low resistance index. The 3-dimension color Doppler revealed branch-shape blood flow for IH and CH. IH showed one supply artery and CH showed two( χ2=3.948, P=0.047). Compared with the three kinds of CH, NICH is mostly mixed echo, RICH is mostly hypoechoic, the maximum diameter and thickness of RICH and PICH lesions are larger than NICH ( t=3.411, P=0.002; t=4.200, P<0.001; t=2.552, P=0.015; t=3.016, P=0.015). The vascular density of NICH is higher than RICH and PICH ( t=-3.209, P=0.002; t=2.485, P=0.016). And the anechoic lumen of PICH lesions is wider than RICH and NICH ( t=2.911, P=0.005; t=2.717, P<0.001). Conclusions:CH lesion was larger than IH one, with visible vessels and calcification on ultrasound, and higher vascular density. The three-dimension color Doppler revealed that IH had one supply artery and CH had two. The maximum diameter and thickness of RICH and PICH lesions are larger than NICH, the vascular density of NICH is higher than RICH and PICH.
