[Multiple erosive discopathies associated with ankylosing spondylitis (author's transl)]. / Discopathies érosives mutifocales au cours d'une spondylarthrite ankylosante.

ABSTRACT

The authors report a case of ankylosing spondylitis affecting a woman with low-back pains. Although initial X-rays did not show any lesions of the spine, one year later, radiographs prove the existence of multiple lesions mimicking spondylodiscitides and characterized by erosions diffusely involving end-plates of cervical, dorsal and lumbar vertebrae. Surgical biopsy at the lumbar site provides an histological evidence of non specific inflammatory lesions.
