Myalgias Soft tissues: There is diffusely increased T2 signal within the anterior compartment of the left thigh specifically involving the vastus lateralis, intermedius, and medius. This also involves the rectus for more subtle but to a lesser degree. Additionally, on the coronal STIR sequence, similar although less severe findings are noted in the contralateral leg. There is no evidence of a focal fluid collection.Osseous structures: Marrow signal of the femora is normal.
Diffuse muscle edema involving the anterior compartment of the left femur consistent with myositis. This is most notable within the vastus lateralis. Similar although less severe findings are noted in the contralateral leg as well. Although evaluation is limited by lack of intravenous contrast, there is no evidence of focal fluid collection.
