摘　　要：目的探讨隐性脊柱裂的超声表现,提高产前超声对此类畸形的认识。方法回顾性分析9例产前诊断为胎儿隐性脊柱裂的超声表现,并与放射影像学资料对比,总结其声像图特点。结果产前超声诊断隐性脊柱裂9例,经尸解、X线摄片或出生后MRI证实,8例诊断正确,另1例为显性脊柱裂。胎儿隐性脊柱裂的超声表现具有特征性,其声像图特点为:①胎儿脊柱正常生理弯曲消失;②病变部位椎骨骨化中心排列异常,椎板缺如,椎管开放;③背部皮肤连续完整,无囊状物突出及胎头形状改变。结论超声检查是诊断隐性脊柱裂的可靠方法。Objective To investgate the ultrasound appearance of prenatal spina bifida occulta （SBO） to improve the recognition of this kind of abnormality. Methods A total of 9 cases of SBO which were diagnosticated by prenatal ultrasound were reviewed retrospectively. The results were compared with radiological and pathological results. Results Prenatal ultrasound diagnosed 9 SBO cases, which were confirmed by autopsy, X-ray or MP, I （8 SBO cases and 1 spinal bifida manifesta cases）. The sonogram features of SBOwere the disaooearance of physiological curvature of spine,abnormal arrangement of intravertebral body in diseased region, the absence of vertebral plate with opening vertebral arch, and the normal skin outline on the back, with out outstanding cyst or the skull.
