title: Butterfly vertebra.
abstract: A 41-year-old man with low back pain and lumbar disc disease was found to have L-3 butterfly vertebra on imaging studies as an incidental finding. This uncommon congenital anomaly of the vertebral column is usually asymptomatic and of no clinical significance. Awareness of this deformity and its imaging features is important diagnostically.
