ABSTRACT A 63-year-old woman presented with abdominal pain and hematochezia was referred for 18F-FDG PET/CT for the underlying malignancy. PET/CT detected diffuse thickening of the bowel walls with intense radioactivity in the colons. She was later diagnosed with multiple myeloma and secondary gastrointestinal amyloidosis, and achieved complete response of myeloma and amyloidosis after 9 cycles of chemotherapy.
