title: The limbus vertebra: an anterior disc herniation demonstrated by discography.
abstract: Limbus vertebra results from an intrabody herniation of disc material. It can be mistaken for a fracture, infection, or tumor, resulting in unnecessary invasive diagnostic procedures. A case is presented in which the lesion was diagnosed by discography. Most radiologists are unfamiliar with discograms, yet they are useful because they opacify the anteriorly herniated portion of the nucleus pulposus.
