Obscured bone metastases after administration of hematopoietic factor on FDG-PET.
We describe interesting imaging features on a FDG-PET scan in a patient with bony metastases from a rare tumor. The lesions were obscured by intense bone marrow activity after the administration of hematopoietic factor at the time of diagnosis. Correlative MRI, CT scan, and pathology findings have also been illustrated. Follow-up FDG-PET scan demonstrated the hypermetabolic lesions.
