Dear all,
I am attaching a case (MRI and CT) of 35 year old men with painless swelling of the shoulder (LHB area) for about 7 months.
The orthopedist asked for a rotator cuff tear.
The patient had a shoulder ultrasound 2 years ago (…I do not have the images or the report !!!) of which he tells a modest and unspecified inflammation of the biceps and rotator cuff.
In many years I have never seen such a painting!
Thank you very much for your help.
Antonio

Looks like that could be primary synovial osteochondromatosis of the biceps tendon sheath.
Are there lots of little spheres when you scroll through?
