Multimodality Imaging Including PET/CT in a Patient with Amyloid Arthropathy and Multiple Myeloma

We report a case of amyloid arthropathy in a patient with multiple myeloma. Amyloid arthropathy is a very rare condition that may be associated with multiple myeloma. It presented in our patient as soft tissue masses around joints and eroding into adjacent bones. We found it to be hypermetabolic on fused positron emission tomography and computed tomographic scanning.
