Espondiloartritis anquilosante: revisión de hallazgos imagenológicos en la columna

Abstract

Introduction Ankylosing spondyloarthritis (AS) is the most common and representative of seronegative spondyloarthropathy. It is characterised by chronic inflammation of the axial skeleton, leading to chronic back pain and progressive stiffness. It typically occurs in young patients, with symptoms often appearing with peak onset between 20 and 30 years of age, and is strongly associated with human leukocyte antigen B-27 (HLA B-27). Current imaging techniques are central in the management of these patients. The recognition of its classic imaging findings and its complications is essential for radiologists. Objectives To present a pictorial review of the spinal imaging findings in patients with AS. Methods and materials An analysis will be made of the spinal imaging findings in conventional radiography, CT and MRI in multiple patients from our medical centre. The most representative findings, complications, differential diagnoses, and some radiological key points will be shown.
