Prenatal diagnosis of fetal hemivertebrae: A case report

Hemivertebrae is a congenital anomaly of the spine in which one half of the vertebral body develops. it is the most common anomaly causing congenital scoliosis. The incidence of hemivertebrae is around 5-10:10 000 birth. it affected more frequently female. The causes and the mode of inheritance of hemivertebrae are unknown. Isolated fetal hemivertebrae carry a good prognosis but the presence of associated anomalies inclucling musculoskeletal, cardiac, intestinal, renal and intracranial; reduces the survival. We presented a case of thoracal hemivertebrae in a 23 years old primigravid woman at 21 weeks gestational age. in ultasonographic examination was found thoracal kyphoscoliosis due to hemivertebrae formation between lOth and llth thoracal vertebras. There wasn't any other associated anomalies. Amniocentesis was made and fetal chromosomal analysis was normal karyotyp. Prenatal diagnosis of hemivertebrae was confirmed by postpartum radiologic detecting.
