Juvenile Dermatomyositis

Juvenile dermatomyositis is a rare autoimmune inflammatory myopathy characterized by progressive proximal muscle weakness and distinctive skin manifestations. Imaging, particularly MRI, plays a crucial role in diagnosis and monitoring, detecting muscle edema, inflammation, and chronic atrophy. Calcinosis is a common complication, particularly in children, and serves as a marker of disease progression. Treatment primarily involves glucocorticoids, with immunosuppressive agents used to minimize long-term steroid exposure. While remission is achievable, ongoing management is necessary to prevent relapses and complications.
