Prenatal diagnosis of fetal hemivertebra at 20 weeks' gestation with literature review

Abstract

Hemivertebra is a rare congenital spinal malformation, where only one side of the vertebral body develops, resulting in deformation of the spine, such as scoliosis, lordosis, or kyphosis. We present the ultrasonographic features of a fetus with hemivertebra at 20 weeks' gestation confirmed by post mortem radiography and pathological examination. The prenatal literature on this disorder is also reviewed. Useful background information is provided for both clinicians and other health professionals who are not familiar with this condition. © 2010 Varras and Akrivis, publisher and licensee Dove Medical Press Ltd.
