My confusion came from the complete absence of enhancement.In my limited experience imaging stump neuroma over the years (prob < 10) they have all enhanced to some extent.
I’m satisfied that these are stump neuromas
Darryl Sneag responded: Yes, they don’t need to enhance. This is likely fibrous tissue that can have variable and delayed enhancement.

It took me a while to figure out this is an upper arm.There is a distorted smoothly tapered humeral stump.
The head is chronically dislocated.
There is marked atrophy and mild edema of residual upper arm muscles.
I really have NO CLUE….but I was wondering if these could be huge nerve sheath cysts somehow related to the neuropathic atrophy of the arm muscles?
What can these be?
