Butterfly vertebra

Dr Ayush Goel and Radswiki et al.

Butterfly vertebra is a type of vertebral anomaly that results from the failure of fusion of the lateral halves of the vertebral body because of persistent notochordal tissue between them.

Radiographic features

Radiograph

The involved vertebral body is widened, and the bodies above and below the butterfly vertebra adapt to the altered intervertebral discs on either side by showing concavities along the adjacent endplates.

Some bone bridging may occur across the defect which is usually seen in the thoracic or lumbar segments of the spine.
