BACKGROUND
Encephalocele, a rare congenital brain malformation, is herniation of brain tissue with or without meninges through a cranial fossa defect. It is classified by location and is usually associated with other congenital anomalies.
CASE
A 29-year-old G2, P1, 36-week pregnant woman was referred for fetal ultrasound delivery planning. Sonographic abnormalities led to fetal magnetic resonance imaging, which revealed a large sac of cerebrospinal fluid herniating through the anterior cranial fossa defect with strands of neurogenic tissue in direct contact with the tongue in the absence of the palate. Agenesis of the corpus callosum and the classic "Viking helmet" appearance of the frontal horns of the lateral ventricles were clearly visible.
CONCLUSION
Prenatal diagnosis of encephalocele is rarely reported. Unfortunately, the infant in this case report died at 3 months of age despite intensive medical therapy.
背景
脑膨出是一种罕见的先天性脑畸形，是脑组织和（或）脑膜通过颅裂缺损疝出。它根据位置进行分类，通常与其他先天性异常有关。
病例
一位 29 岁 G2P1 的 36 周孕妇因胎儿超声分娩计划而被转诊。超声异常导致胎儿磁共振成像，显示一个大的脑脊液囊通过前颅窝缺损疝出，有神经组织的条索与舌直接接触，没有腭。胼胝体发育不全，侧脑室额角呈典型的“维京头盔”外观。
结论
脑膨出的产前诊断很少见。不幸的是，本例报告中的婴儿尽管接受了强化治疗，但在 3 个月时死亡。
