Abstract：
Congenital tumors are rare, and malignant congenital tumors are uncommon. Benign tu,mors might be life-threatening, depending on the location and size of the tumor. Different factors affect congenital tumors, such as maternal and placental hormones and environmental factors such as drugs, radiation, and infection. Developing fetal imaging methods and continuous follow-up during pregnancy are important factors in congenital tumor prognosis. Ultrasound is the most common method used for fetal evaluation. The complementary evaluation method is MRI. Both methods are helpful and widely spread for the detection of congenital tumors. These imaging methods help the medical team make a suitable decision about therapy. Some of these tumors regressed spontaneously, and some need surgical treatments. Treatment of tumors has developed rapidly, and recently molecular-targeted drugs have been used.
摘要：
先天性肿瘤很少见，恶性先天性肿瘤并不常见。良性图，Mors可能会危及生命,取决于肿瘤的位置和大小。不同因素影响先天性肿瘤，如母体和胎盘激素和环境因素如药物，辐射,和感染。开发胎儿影像学检查方法和孕期连续随访是影响先天性肿瘤预后的重要因素。超声是用于胎儿评估的最常用方法。补充评估方法是MRI。这两种方法对先天性肿瘤的检测都很有帮助，并且广泛传播。这些成像方法帮助医疗团队做出合适的治疗决定。其中一些肿瘤自发消退，有些需要手术治疗.肿瘤的治疗发展迅速,最近已经使用了分子靶向药物。
