Abstract:
A 74-year-old woman who had developed numbness in both hands was diagnosed as having bilateral carpal and right cubital tunnel syndrome and underwent bilateral carpal and right cubital tunnel release. Transthyretin immunoreactive amyloid deposits were seen on specimens and were also detected in gastric, duodenal and ileal mucosal biopsies. The transthyretin gene analysis showed no mutation. This is a rare case of senile systemic amyloidosis presenting as carpal tunnel syndrome.
