胎儿骶尾部脊膜膨出的超声诊断(附6例报告)

UItrasonic diagnosis of spinal meni ngocele in sacrococcygeal region of fetus

目的探讨超声对胎儿骶尾部脊膜膨出的诊断价值。方法对6例经病理学证实的胎儿骶尾部脊膜膨出的超声影像资料进行回顾性分析。结果超声征象表现为,胎儿脊柱纵行扫查时呈现的两条平行光带于骶尾部出现部分中断,骨质缺损,此处有囊性包块向背侧膨出,大小不一,囊壁薄,仅为一层膜样结构,囊内为无回声液性暗区。其中4例合并羊水过多。结论产前超声检查对胎儿骶尾部脊膜膨出有重要的诊断及鉴别诊断价值。

Objective To evaluate the role of ultrasound in the diagnosis of spinal meningocele in sacrococcygeal region of fetus.Methods The ultrasonic characteristics of s ix cases with pathologically proven spinal meningocele in sacrococcygeal region were analyzed retrospectively.Results When fetal spinal was scanned longit udinally it was found that two parallel light -bands were broken partly wi th the defect of osseous tissue in sacrococcygeal region where a cystiform mass of different size inflated backward.The cystiform mass surrounded by only one layer of thin lemma was fil led with anechoic fluid.Four cases h ad complicated polyhydranmios.Conclusion Pre -natal ul-trasound examination has important value in the diagnosis and different ial diagnosis of spinal meningocele in sacrococcygeal region of fetus.[
