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

Area of Science:

• Rheumatology
• Pediatric Rheumatology
• Medical Imaging

Background:

• Juvenile dermatomyositis (JDM) is an autoimmune disease affecting children.
• Calcinosis and lipodystrophy are significant JDM complications, impacting up to 20% of patients.
• Calcinosis onset typically occurs 1-3 years post-JDM diagnosis.

Observation:

• A case of JDM with severe calcinosis and lipodystrophy is presented.
• Various imaging modalities were employed to evaluate the extent of calcinosis.
• Bone scintigraphy revealed increased uptake in the right scapula.

Findings:

• Multiple subcutaneous calcifications were observed on the shoulder and back.
• Inflammatory imaging features were noted in the right knee joint.
• Imaging confirmed widespread calcifications and active inflammation in JDM.

Implications:

• Comprehensive imaging is crucial for evaluating JDM-related calcinosis severity.
• Accurate assessment aids in treatment planning and monitoring disease progression.
• Understanding imaging findings can improve patient outcomes in JDM.
