Prenatal sonographic diagnosis of the congenital dislocated spine: a case report.

Abstract

A case of congenital dislocated spine diagnosed by prenatal sonography is reported. To report the first documented case of prenatal diagnosis, to point out the characteristic features of prenatal sonography of congenital dislocation of the spine, and to show the results of a careful management of birth in cases of congenital dislocated spine. The congenital dislocated spine consists of an anterior defect in formation of the vertebrae with a displaced vertebra and angulation of the neural canal. Instability and the consequent possibility of neurologic damage are the major features of this rare entity. Early intervention is essential to prevent an irreparable neurologic deficit. Pre- and postnatal imaging was reviewed. Early postnatal treatment is described. Prenatal diagnosis of the congenital dislocated spine can be detected with sonography and confirmed by radiography and magnetic resonance imaging. Prenatal diagnosis of the congenital dislocated spine is of the utmost importance for parental counseling and obstetrical management.
