Hemivertebrae rad iograph12/12/2023 We present a case of congenital scoliosis due to hemivertebra detected prenatally and the ultrasonic findings that led to the diagnosis.Ī 30‑year‑old Hispanic woman, G 2P 1 was referred at 23 weeks gestational age for evaluation of a possible neural tube defect detected on an ultrasound performed elsewhere. There are few reports concerning the ultrasonographic diagnosis of fetal hemivertebra 1‑3. Hemivertebra, a condition where there is complete unilateral failure of the vertebral body to form, is a common cause of congenital scoliosis. MESH Hemivertebra of thoracic vertebrae ICD9 756.14 CDC 756.155Ĭongenital scoliosis is caused by the abnormal development of the vertebrae. Standard obstetrical management for isolated hemivertebra. Management: Dependant upon associated anomalies. Recurrence risk: Rare, however, there may be a 4% risk of neural tube defects in siblings. Isolated hemivertebra carries good prognosis. Prognosis: Dependant upon associated anomalies. May be part of a syndrome: Jarcho‑Levin, Klippel‑Fiel, VACTERL.ĭifferential diagnosis: Neural tube defects, other causes of congenital scoliosis (wedge vertebra, butterfly vertebra, bloc vertebra). Other associated anomalies include cardiac, renal, central nervous system and gastrointestinal. Pathogenesis: Developmental failure of one of the lateral vertebral chondrification centers.Īssociated anomalies: Musculoskeletal system including ribs, spinal cord and limbs. Prevalence: 5‑10:10,000 births, occurs more commonly in females.Įtiology: Sporadic versus multifactorial inheritance. Synonyms: Congenital scoliosis (one of the causes of), unilateral aplasia of the vertebral body, complete unilateral failure of formation of the vertebral body.ĭefinition: Congenital malformation of the spine in which only half of a vertebral body develops.
