title: Amyloidosis in FDG-avid lymph nodes.
abstract: Amyloidosis in lymph node that is FDG-avid is an unusual diagnosis. FDG PET/CT showed the presence of multifocal lymphadenopathy mainly axillary with a mesenteric mass. Surgical lymph node biopsy with histological examination confirmed the diagnosis of amyloidosis in a 64-year-old woman with an initial left axillary pain. Amyloidosis should be considered on the differential diagnosis for a FDG-avid lymphadenopathy. Other differential diagnosis usually includes malignancy such as lymphoma or metastatic disease, infection, or sterile inflammation.
