Reason: polymyositis History: same. Right Femur:Metallic artifact from right hip arthroplasty device limits evaluation. Previously seen abnormal signal within the distal aspect of the vastus medialis has significantly decreased compared to prior. Previously seen abnormal signal within the adductor magnus has decreased compared to prior. Additional previously seen smaller foci of abnormal signal within the vastus intermedius, gluteus medius and minimus have resolved. No new sites of abnormal signal. No significant fatty muscle atrophy.Left Femur:Metallic artifact from right hip arthroplasty device limits evaluation. Previously seen abnormal signal within the adductor magnus has decreased compared to prior. Previously seen abnormal signal within the biceps femoris has resolved. No new sites of abnormal signal. No significant fatty muscle atrophy.
Interval decrease or resolution of previously seen muscle edema compatible with resolving polymyositis.
