Targeted biopsy of the ulnar nerve for amyloidosis with potential implications of a diagnostic and nondiagnostic biopsy: illustrative case
The positive biopsy of the ulnar nerve fascicle allowed targeted treatment of the neural amyloidosis. While the negative biopsy of the triceps branch could be attributed to sampling error, it could also be due to the fact that this branch found within the ulnar nerve is thought to originate from the radial nerve. https://thejns.org/doi/10.3171/CASE25484.
