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.
All patients often suffer from vertebral segmentation abnormalities. Those with the dominant variant have, at most, a single butterfly vertebra. [2] Those with the recessive form, however, may suffer from hemivertebrae, vertebral fusion, and rib anomalies. Some cases resemble Jarcho-Levin syndrome or spondylocostal dysostosis. [1]
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 ...
Bertolotti's syndrome is a commonly missed cause of back pain which occurs due to lumbosacral transitional vertebrae (LSTV). It is a congenital condition but is not usually symptomatic until one's later twenties or early thirties. [1] However, there are a few cases of Bertolotti's that become symptomatic at a much earlier age.

Klippel–Feil syndrome (KFS), also known as cervical vertebral fusion syndrome, is a rare congenital condition characterized by the abnormal fusion of any two of the seven bones in the neck (cervical vertebrae). [1]: 578 It can result in a limited ability to move the neck and shortness of the neck, resulting in the appearance of a low hairline ...
