Myositis, in the musculoskeletal (MSK) context, refers to the inflammation of muscles, leading to weakness, swelling, and pain. This condition can be caused by various factors, including infections, autoimmune disorders, injuries, or certain medications. Diagnosing myositis often involves a combination of clinical evaluation, blood tests to identify muscle enzyme elevations, and imaging studies.
Medical ultrasound plays a crucial role in the diagnosis and monitoring of myositis. Sonographic findings can include muscle edema, increased echogenicity, fascial thickening, and sometimes, fluid collections. Ultrasound is valuable for guiding muscle biopsies and assessing treatment response, making it a key tool in the comprehensive management of myositis within musculoskeletal medicine.
