title: ["Cupid's bow" contour of the lumbar vertebrae].
abstract: The cortical margin of the inferior end plate of lumbar vertebral bodies, in the frontal projection, frequently simulates the curvature of a bow, aimed cephalad. On lateral view, the two concavities are superimposed and lie in the posterior portion of the vertebral body. The aspect, called "Cupid's bow" must be considered a normal anatomic variant and should not be confused with diseases affecting the spine. The incidence and degree of the finding are discussed.
