To investigate two-dimensional sonographic features of fetal solitary hemivertebra
and to improve the awareness of prenatal ultrasonography.
Methods:
From May 2010 to May 2015
36 504 pregnant women in Chashan Hospital of Dongguan underwent routine prenatal ultrasound examination. Seven cases of fetal solitary hemivertebra were retrospectively analyzed.
Results:
There were five cases of thoracic hemivertebra and two cases of lumbar hemivertebra. During prenatal ultrasound examination
five cases of kyphosis or lordosis were found in sagittal section
and six cases of left or right spinal scoliosis were found in coronal section. In the absence of scoliosis and angulation it was very difficult to find vertebral m
orphological abnormalities in cross section.
Conclusion:
Sagittal section could display kyphosis or lordosis caused by hemivertebra
coronal section could display left or right spinal scoliosis
and cross section could display vertebral morphological abnormalities. Fetal solitary hemivertebra has typical sonographic features
and two-dimensional ultrasound could be used for screening of fetal solitary hemivertebra.
