A precise prenatal diagnosis of hemangioma may be uncertain although a variety of the antenatal appearances on 2-dimensional sonography have been reported. A 27-year-old primigravida was referred at 32 weeks of gestation for evaluation of a fetal nuchal mass. Two-dimensional sonography showed an extracranial mixed echogenic mass (65 x 54 x 59 mm) occupying the posterior neck. Color Doppler imaging revealed intense hypervascularization. Three-dimensional (3D) and 4-dimensional (4D) sonography showed that the mass was lobulated, with a lumpy internal structure. Nuchal hemangioma was further confirmed by clinical examination and postnatal magnetic resonance imaging. The tumor began to regress in size when the infant was 7 months old. Prenatal 3D/4D ultrasound techniques could be considered as complementary diagnostic tools for such a tumor. They have the advantages of providing accurate and inexpensive virtual reality images through more realistic interactions with the virtualized in utero condition.
尽管已有多种二维超声产前表现的报道，但血管瘤的精确产前诊断仍可能存在不确定性。一名27岁初产妇在妊娠32周时因胎儿颈部肿块前来评估。二维超声显示一个颅外混合回声肿块（65×54×59毫米）占据后颈部。彩色多普勒成像显示强烈的血管过度增生。三维（3D）和四维（4D）超声显示肿块呈分叶状，内部结构呈块状。经临床检查和产后磁共振成像进一步证实为颈部血管瘤。婴儿7个月大时，肿瘤开始缩小。产前3D/4D超声技术可被视为此类肿瘤的辅助诊断工具。它们具有通过与子宫内虚拟状况进行更逼真的交互来提供准确且廉价的虚拟现实图像的优势。
