[Spinal hemangioma in the roentgen picture of the Andersson lesion in ankylosing spondylitis].

The vertebral cavernous hemangioma is described as the number five cause in the etiology of the Andersson lesion (vertebral-discal destruction in ankylosing spondylitis). In one case of a completely stiffened spine, radiographs showed a vertebral hemangioma with a cockade-like appearance instead of the typical coarse-striated osseous structure. Histologic necropsy results were those of a cavernous vertebral hemangioma. The immobile rigid spine, that is, the pathologically disturbed function appears to have a strong influence on the form, structure and pathology.
