Abstract:
Objective To observe the muscles and skeleton involvement surrounding sacroiliac joint (SIJ) of axial seronegative spondyloarthropathy (SPA) patients with magnetic resonance imaging (MRI),and to analyze the relationship between them.Methods A prospective study of 38 patients who meet the 2009 axial SpA diagnostic criteria was conducted.We carried out MRI of the SIJ for these patients to evaluate the muscles and skeleton involvement.Those cases were divided into muscles differences between the two groups of image scores,including Spondyloarthritis Research Consortium of Canada (SPARCC) scores and Spondyloarthritis Research Consortium of Canada MRI Sacroiliac Joint Structural Score (SPARCC SSS).The extent of muscles edema in patients with sacroiliac joints was ranked into twelve grades from 0-12,and we did Spearman rank correlation test of muscles edema scope and two indexes.Results We found that 28 cases (73.68%) of the 38 patients had significant muscle involvement by analyzing the STIR sequence,and found erector spinae in 22 cases (57.89 %)gluteal muscles in 13 cases (34.21 %),iliacus muscle in 11 cases (28.95 %),obturator muscle in 5 cases (13.16%),piriform muscle in 5 cases (13.16%) and other 4 cases (10.53%).SPARCC (t =2.28,P =0.03) and SPARCC SSS (t =3.37,P =0.00) were statistically different between the two groups.SPARCC (P =0.00,r =0.67) and SPARCC SSS (P-0.01,r =0.47) were positively correlated with the extent of muscles edema.Conclusions The muscles edema around sacroiliac joint is an important sign of axial SpA magnetic resonance imaging.Patients who had muscles edema tended to have more serious skeleton changes.
