[Congenital absence of a pedicle of the thoracic vertebrae. A new case].
The authors report a case of congenital absence of pedicle in the thoracic spine which is uncommon. The lesion may occur at three stages of vertebral development: membranous, cartilaginous or osseous. Careful examination of the X-rays allows visualisation of pedicle aplasia or hypoplasia, associated with controlateral and posterior arch lesions, confirming the congenital origin. Computed tomography scan allows careful analysis of the lesions and eliminates others causes of absence of pedicle, avoiding invasive and expensive explorations.
