With recent advances in technology, fetal sacrococcygeal teratoma is being diagnosed increasingly during the early prenatal period by ultrasound examination. In addition, early detection of tumor related complications such as polyhydramnios, congestive heart failure, hydrops, hemorrhage, urinary tract or bowel obstruction can be followed closely in utero. Active prenatal management can improve fetal perinatal outcome by allowing planned delivery for neonatal surgery [Chisholm, C.A. et al.: Am J Perinatol 1999;16:47-50] or in some cases, fetal intervention. Additionally, families can be counseled appropriately regarding the range of outcomes. We report a case of fetal sacrococcygeal teratoma Type I diagnosed at 20 weeks with a prominent vessel supplying the tumor mass. At 23 weeks, there was a sudden appearance of an additional lobular mass, consistent with intrauterine spontaneous ruptured of a sacrococcygeal teratoma mass.

随着技术的最新发展,在产前早期,通过超声检查越来越多地诊断出胎儿sa尾畸胎瘤。此外,早期发现与肿瘤相关的并发症,如羊水过多,充血性心力衰竭,积水,出血,尿路或肠梗阻,可在子宫内密切随访。积极的产前管理可以通过允许新生儿手术的计划分娩来改善胎儿围产期结局 [Chisholm,c.a等人: Am J Perinatol 1999;16:47-50] 或在某些情况下,进行胎儿干预。此外,可以就结局的范围向家庭提供适当的咨询。我们报告了一例在20周时诊断为I型胎儿sa尾畸胎瘤的病例,其中有突出的血管供应肿瘤。在第23周时,突然出现了额外的小叶肿块,与子宫内自发性sa尾畸胎瘤破裂一致。
