Reason: myositis History: weakness. Interval resolution of edema signal intensity within the musculature bilaterally. Severe muscle fatty atrophy of the supraspinatus, infraspinatus, teres minor, and subscapularis muscles bilaterally. The supraspinatus, infraspinatus, teres minor, and subscapularis tendons are intact. The remainder of the soft tissue structures are within normal limits. Bone marrow signal intensity is within normal limits.
Interval resolution of muscle edema. Severe fatty muscle atrophy of the rotator cuff muscles.
