Using imaging methods to assess severe calcinosis in juvenile dermatomyositis: A case report

Calcinosis and lipodystrophy are severe complications of juvenile dermatomyositis (JDM). Up to 20% of patients have calcinosis, and the onset of calcinosis usually occurs 1 to 3 years after that of the illness. We report a case of JDM with severe complications of calcinosis and lipodystrophy, and we assess calcinosis using a variety of imaging methods. To evaluate the patient's inflammatory state, bone scintigraphy was performed, which demonstrated increased uptake in the right scapula, in addition, multiple calcifications are present subcutaneously on the shoulder and back, and inflammatory imaging features are also present in the right knee joint.
