Sumario: | Background: Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease among children. In some patients, cervical spine arthritis remains a serious and chronic manifestation of JIA. The aim of this study was to assess the frequency of cervical spine lesions on radiographs and MRI in JIA patients with clinical signs of cervical spine involvement and to verify if with the addition of MRI, the use of radiographs could be abandoned. Methods: This retrospective study evaluated consecutive 34 children (25 girls; aged 6–18 years, median 15.5 years) with JIA and with clinical involvement of cervical spine. In each patient, both radiographs and MRI of the cervical spine were performed. Imaging findings were correlated with clinical and laboratory data. Results: The cervical spine was affected in 35% of patients. The most frequent lesions were subaxial subluxations (SAS; 24%), apophyseal joint ankylosis (9%), and C1/C2 joint lesions (9%). Anterior atlanto-axial subluxation (AAS) was diagnosed only by radiography, and most of the SAS were seen on radiography, whereas only a few on MRI. Reversely, C1/C2 soft tissue involvement were seen on MRI only. Cervical spine involvement was associated with raised ESR (p = 0.012) and CRP (p = 0.014). Conclusions: The cervical spine lesions are still frequent complication of JIA affecting up to 35% of JIA patients. Most of them develop serious complications, such as AAS and ankylosis. Despite advantages of MRI in terms of the imaging of the atlanto-axial region radiography shows superiority in diagnosis of AAS and SAS. |
