Congenital brain tumors are rare and, whether diagnosed prenatally or postnatally, the most frequent type is teratoma. Prenatal diagnosis relies on sonography and magnetic resonance imaging, and is usually achieved during the second or third trimester. We report a case of an intracranial tumor diagnosed in the early second trimester. The diagnosis had been suspected at first-trimester routine sonography, which showed a compressive intracranial mass with mild vascularization. Because of the poor prognosis, termination of pregnancy was discussed with the parents and was carried out at 14 weeks of gestation. Postmortem examination provided a diagnosis of right frontal immature teratoma.
先天性脑肿瘤较为罕见，无论产前还是产后诊断，最常见的类型是畸胎瘤。产前诊断依靠超声检查和磁共振成像，通常在孕中期或晚期进行。我们报告一例在孕中期早期诊断出的颅内肿瘤病例。在孕早期常规超声检查时就怀疑有该诊断，超声显示颅内有一个有轻度血管化的压迫性肿块。由于预后不良，与患儿父母讨论了终止妊娠，并在妊娠14周时实施。尸检诊断为右额叶未成熟畸胎瘤。
