Figure 11From: Ultrasonography and color Doppler of proximal gluteal enthesitis in juvenile idiopathic arthritis: a descriptive studyUS and MRI images of a 15 year old boy with JIA and enthesitis. A) Fat suppressed T2-weighted MRI sequence showing bilateral, physiological edema of the iliac crests (arrows). Focal muscle edema at the left gluteus medius insertion (arrowhead) indicates enthesopathy. B) Longitudinal US with CD of the left insertion showing a hypoechoic area and hyperemia. C) T1-weighted MRI sequence before intravenous gadolinium contrast injection. D) Fat suppressed T1 sequence after contrast injection showing enhancement (arrowhead) in the muscular insertion.Back to article page
