骶前部脑膜膨出是一种极其罕见的疾病，之前只有一份产前诊断报告。我们报告了一名 36 岁初产妇的病例，她在妊娠 19 + 4 周的常规超声检查中发现巨大的胎儿盆腔囊肿后被转诊。妊娠 20 + 5 周时，胎儿超声和磁共振成像 (MRI) 均无法检测到囊肿与脊髓之间的通讯。由于梨形囊肿穿过盆腔隔膜延伸至会阴，让人想起扩张的阴道和子宫颈，因此初步诊断为继发于处女膜闭锁的子宫阴道积水。在妊娠 33 + 5 周的随访 MRI 中，清晰地描绘出一条通过骶前孔连接盆腔囊肿和椎管的狭窄柄，使我们能够产前诊断骶前脑膜膨出。版权所有 © 2011 ISUOG。由约翰·威利父子有限公司出版
Anterior sacral meningocele is an extremely rare condition and there has been only one previous report of a prenatal diagnosis. We report the case of a 36‐year‐old primigravida who was referred following detection of a huge fetal pelvic cyst on routine ultrasound examination at 19 + 4 weeks' gestation. Neither fetal ultrasound nor magnetic resonance imaging (MRI) at 20 + 5 weeks' gestation could detect communication between the cyst and the spinal cord. Because extension of the pear‐shaped cyst through the pelvic diaphragm down to the perineum was reminiscent of dilated vagina and uterine cervix, a tentative diagnosis of hydrometrocolpos secondary to imperforate hymen was considered. On follow‐up MRI at 33 + 5 weeks' gestation, a narrow stalk connecting the pelvic cyst and the spinal canal through the anterior sacral foramen was clearly delineated, allowing us to reach the prenatal diagnosis of anterior sacral meningocele.
