title: 11C-PiB PET/CT in nasopharyngeal amyloidosis associated with multiple myeloma.
abstract: We present an unusual case of nasopharyngeal amyloidosis associated with multiple myeloma. A 63-year-old woman presented with 2 months' history of epistaxis and dentalgia 3 years after being diagnosed with multiple myeloma. CT and C-Pittsburgh compound B (PiB) PET images demonstrated that the intense C-PiB uptake corresponded to the nasal, paranasal, and palatal area matching the CT mass lesion. Histopathologic examination confirmed amyloidosis.
