The authors report a case of a lipomyelomengocele with tethered cord, revealed on prenatal ultrasonography and confirmed by fetal magnetic resonance imaging (MRI).
A 32-year-old woman, gravida 1 para 1 underwent the routine second trimester prenatal ultrasound scan at 22(+5) weeks of gestation at the present hospital.
The scan indicated an echoic semisolid subcutaneous mass covered by skin, posterior to the lumbosacral spinal canal of the fetus. Based on the findings indicating occult dysraphism, a fetal MRI examination was conducted, revealing that the mass was extending to the spinal cord, tethering the cauda equina. The diagnosis of lipomyelomeningocele was established.
Lipomyelomeningocele is a form of closed neural tube defect with unclear predisposing factors. Its prevalence ranges between 0.3 and 0.6 per 10,000 live births. It leads to progressive conus tethering with associated neurological, urinary, and gastrointestinal deficits, demonstrating the importance of prenatal diagnosis.
作者报告一例产前超声检查发现并经胎儿磁共振成像（MRI）证实的脂肪瘤型脊髓脊膜膨出合并脊髓栓系病例。
一名32岁经产妇，孕1产1，在本院妊娠22（+5）周时接受了常规孕中期产前超声检查。
超声检查显示胎儿腰骶椎管后方有一个被皮肤覆盖的回声性半固体皮下肿块。基于提示隐性神经管闭合不全的检查结果，进行了胎儿MRI检查，发现肿块延伸至脊髓，牵拉马尾神经。确诊为脂肪瘤型脊髓脊膜膨出。
脂肪瘤型脊髓脊膜膨出是一种闭合性神经管缺陷，其诱发因素尚不清楚。其发病率为每10000例活产中有0.3至0.6例。它会导致圆锥渐进性栓系，并伴有相关的神经、泌尿和胃肠道功能障碍，这表明产前诊断很重要。
