Butterfly vertebra (also known as sagittal cleft vertebra) is a rare congenital spinal anomaly characterized by the presence of a sagittal cleft within a vertebral body, giving it a butterfly-like appearance on imaging. This condition arises due to incomplete fusion of the lateral halves of a vertebra during embryonic development.
Butterfly vertebrae have a sagittal cleft through the body of the vertebrae and a funnel shape at the ends. This gives the appearance of a butterfly on an x-ray. It is caused by persistence of the notochord (which usually only remains as the center of the intervertebral disc) during vertebrae formation. There are usually no symptoms.
Diastematomyelia is a "dysraphic state" of unknown embryonic origin, but is probably initiated by an accessory neurenteric canal (an additional embryonic spinal canal.).) This condition may be an isolated phenomenon or may be associated with other segmental anomalies of the vertebral bodies such as spina bifida, kyphoscoliosis, butterfly vertebra, hemivertebra and block vertebrae which are ...
Other presentations of Alagille's syndrome include butterfly vertebrae, ophthalmic defects, and distinct facial structures. The butterfly vertebrae can be detected with an x-ray, but there typically are no symptoms from this abnormality. Other skeletal defects common in ALGS patients are spina bifida and the fusion of vertebrae. [10]
The four main divisions of the spinal column, from top to bottom: cervical, thoracic, lumbar, and sacral. The lateral grey column (lateral column, lateral cornu, lateral horn of spinal cord, intermediolateral column) is one of the three grey columns of the spinal cord (which give the shape of a butterfly); the others being the anterior and posterior grey columns.

Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
