36-year-old male with recurrent Ewing's sarcoma to the right shoulder. Patient is status post radiation. Evaluate response to treatment and for disease progression. The axillary mass seen on the previous study was not imaged in its entirety on the current study. The patient has been contacted and will return for further imaging at no charge at which time an addendum will be logged.There is intermediate signal intensity within the supraspinatus tendon indicating tendinosis. There is mild edema type signal intensity and enhancement of the teres minor muscle which appears more pronounced on the current study which is nonspecific and could represent sequela of radiation therapy, myositis or early denervation atrophy.The acromioclavicular joint appears normal. No frank fluid is is present in the subacromial/subdeltoid bursa.There is linear increased signal intensity separating the anterosuperior labrum from the glenoid likely representing a normal variant sublabral foramen. There is also amorphous low signal intensity between the anterior labrum and subscapularis muscle which appears similar to prior study with no appreciable enhancement or uptake on recent PET scan and may represent scar tissue or thickened ligamentous structures from prior trauma.We see no joint effusion or synovitis.There is curvilinear intermediate signal within the extra-articular tendon of the long head of the biceps that may represent a partial thickness tear but appears similar to prior study and not necessarily of any current clinical significance.As stated previously, the axillary mass seen on the previous study is not visualized in its entirety on the current study and measurements will be provided when the patient returns for further imaging. The mass may represent confluent lymphadenopathy. There are a few additional subcentimeter enhancing lymph nodes again noted more superiorly within the axilla and beneath the clavicle which are unchanged.We see no focal bone marrow lesions.
1. Incomplete evaluation of the patient's axillary mass. Patient has been contacted and will return at which point measurements and evaluation of the patient's mass will be made. Small enhancing lymph nodes in the axilla and clavicle appear similar.2. Mild edema type signal and enhancement of the teres minor muscle which is nonspecific and could represent sequela of radiation therapy, myositis or early denervation atrophy.3. Mild supraspinatus tendinosis and other findings as described above.
