We present a case of both F-FDG and F-florbetapir uptake in a biopsy-confirmed immunoglobulin light chain (AL) amyloidosis involving the peripheral nerves. AL amyloidosis is the most common cause of acquired amyloid polyneuropathy, manifesting with both sensorimotor and autonomic neuronal dysfunction. Given the overlapping MRI and FDG PET/CT appearances of several different causes of peripheral neuropathy, F-florbetapir PET/CT provides another potential tool in the imaging algorithm of these patients and may guide targeted fascicular biopsy for pathologic confirmation.
