A 69-year-old man with recurrent multiple myeloma underwent FDG PET/CT evaluation. A pulmonary nodule without higher-than-background FDG avidity was later biopsied as a low-grade neuroendocrine tumor. On further Ga-68-DOTATATE PET/CT evaluation of patient's neuroendocrine tumor, the lytic myeloma lesions revealed only mild DOTATATE avidity while the primary pulmonary neuroendocrine tumor showed intense DOTATATE uptake. The distinct imaging characteristics of different primary malignancies correlated with their underlying different pathology.
