Abstract:
We report the case of a 55-year-old woman with a 6-month history of progressive paresis of the right radial nerve. Perioperative imaging detected a spindle-shaped expansion of the radial nerve caused by an isolated local deposit of amyloid (amyloidoma). The deposit was resected in 2 phases and the resulting defect was bridged by a sural nerve autograft. Overall internal and hematological examination did not reveal systemic amyloidosis or lymphoproliferative disorder. The reason for our report is that localized forms of amyloid neuropathy are very rare.
