Female 26 years old with new onset upper and lower extremity weakness. Is there any evidence of myositis anywhere? Additional history from the medical record indicates a skeletal muscle biopsy with features suggestive of dermatomyositis. Evaluation is slightly limited due to motion artifact.There is diffusely increased T2 signal within and surrounding all muscles in the flexor, extensor, abductor and gluteal musculature bilaterally. In addition, there is diffuse subcutaneous edema most pronounced along the medial and lateral aspects of the thigh.Bone marrow signal intensity is within normal limits.
Bilateral symmetric increased T2 signal within and surrounding the musculature of the lower pelvis and femur consistent with an inflammatory myopathy.
