Proximal muscle weakness, atrophy, concern for autoimmune etiology/myositis. Evaluate for abnormality. Limited images of the bilateral femurs demonstrate no abnormal T1 or T2 signal within the musculature to suggest atrophy or inflammation/edema. The muscles are bilaterally symmetric. Bone marrow signal is within normal limits.
No specific evidence of abnormality of the thigh musculature.
