Is this findings from my upper left arm anything to worry about results from a MRI?

MRI HUMERUS W WO CONTRAST LEFT COMPLETED TIME: 06/25/2020 10:01

INDICATION: f/u sarcoma

IMPRESSION:
1. Postsurgical changes left shoulder and proximal arm. No evidence of residual or recurrent tumor.
2. Suspect multifocal posttreatment related changes proximal humeral diaphysis and metaphysis as described.

COMPARISON: March 26, 2020

DISCUSSION: Sagittal axial and coronal images left mid and proximal humerus prior to and following administration 17 mL MultiHance. Proximal and distal margins surgical site marked cutaneously.

Postsurgical changes superficial soft tissues lateral proximal arm and shoulder. Associated fibrosis, unchanged. No cystic/solid or enhancing soft tissue mass identified surgical site. Again noted intramedullary abnormality proximal humeral diaphysis. Ill-defined increased signal intensity T2-weighted pulse sequences with enhancement. No interval progression. New and ostial marrow edema and enhancement more proximal medial humeral diaphysis. New versus increased marrow signal abnormality proximal humeral metaphysis. Suspect sequelae prior radiation treatment. Proximal humeral diaphyseal lesion may present focal stress response. Proximal humeral metaphyseal lesion may represent prominent intramedullary vascularity.

Small glenohumeral joint effusion. Diffuse synovial enhancement. Enhancement also present articular aspect distal subscapularis tendon. Findings consistent with partial thickness tear. Overall appearance unchanged. Suspect nondisplaced anterior and posterior glenoid labral tear. If further assessment warranted, recommend dedicated shoulder MRI.

Judging just from your report, I'd say no, but my being a radiologist, I'm limited by not being able to see the images. However, I'd have to say that unless you have some strenuous workout regimen, stress reaction in the humeral diaphysis would be most unusual. In adults, mid-diaphyseal lesions are typically considered until proven non-aggressive. I'd ask for
diffusion weighted images, which is sort of the MRI equivalent to a PET scan....in other words, DWI can help discern between benign and malignant findings. It's basically a 90 second sequence that they should do without extra charge.
Hope this helps and all the best...
