Abstract

In this study, we present two cases of infiltrative, localized amyloidosis involving lumbosacral root and plexus, e.g., isolated amyloidomas. Rare and poorly understood amyloidomas may occur in both neurologic and non-neurologic tissues. The described cases emphasize potential for localized peripheral amyloidomas: (1) potential for associated λ light chain lymphoplasmacytic lymphoma association; (2) e isolated amyloidosis without evidence for systemic plasma cell dyscrasia; (3) features suggestive of potential pathogenesis; and (4) discussion of treatment options including immunotherapy and resection. The limited literature and experience among other cases is described.
