Hi Mike,
Was the image taken at 19:13:58 after you injected the bursa?
It looks like a fair bit of fluid in the bursa,
The other images don’t really show any definite pathology,
The small vessel and little defect in the bone are likely related to the attachment of the superior glenohumeral ligament. I occasionally see a small bony defect in that location and I don’t really consider it pathological.
The flow is interesting, but not really in the correct location to represent GH joint synovitis.
I am not seeing any clear diagnosis on the images to account for the symptoms.
Your images are great quality.
Nice scanning.
Steve
