Presentation
Right shoulder pain that is worse on movement.
Patient Data
There is a focal area of thickening and hyperintensity involving the right suprascapular nerve in the entrance to the right suprascapular notch in keeping with focal stenosing neuritis. The remainder of the brachial plexus is otherwise unremarkable with no neuritis or avulsion injury.
Case Discussion
The suprascapular nerve is a branch of the brachial plexus (upper trunk). It has both sensory and motor innervations; sensory for the acromioclavicular and glenohumeral joints, and motor innervations to the supraspinatus and infraspinatus muscles. This nerve passes through narrow structures making it more prone to compression injuries specifically at the suprascapular and spinoglenoid notches. compression or neuropathy can be caused by trauma, traction injuries, fractures, tears and dislocation 1.
