64-year-old female with proximal muscle weakness. Evaluate for inflammatory myopathy. Moderate to severe degenerative changes affect both hips, right greater than left. There is associated increased bone marrow signal abnormality within the femoral heads and acetabuli, likely reflecting degenerative signal abnormality. There is osteophyte formation, subchondral cysts, and joint space narrowing. There is no increased signal abnormality within the imaged musculature of the left thigh to suggest myositis, as clinically questioned. There is no abnormal enhancement on postcontrast sequences. There is nonspecific subcutaneous edema along the lateral aspect of the vastus lateralis muscle.
Degenerative osteoarthritic changes of both hips without evidence of inflammatory myopathy as clinically questioned.
