F-FDG Uptake in a T2 Hypointense Paraspinal Mass

Academic Article


  • We present a paraspinal amyloidoma found incidentally in a 77-year-old man during lymphoma workup by F-FDG PET/CT. A solitary FDG-avid paraspinal lesion was seen at T11-T12. MRI showed T2 hypointensity and enhancement. Lymphoma was considered the primary differential due to FDG uptake, but biopsy revealed nodules of extracellular acellular homogeneous material with apple-green birefringence on Congo red stain consistent with amyloidoma. Spinal amyloidoma is rare with few cases reported so far in literature.
