title: False-positive 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) findings of bone metastasis from esophagogastric cancer: report of two cases.
abstract: We report two cases of (18)F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) fusion imaging showing false-positive findings of bone metastases from esophagogastric cancer. Although multiple bone metastases from esophagogastric cancer were suggested by several images, ultimately, degeneration of the bone marrow was diagnosed histologically. We discuss the value of imaging modalities and the importance of a comprehensive diagnosis based on a combination of physical examination, laboratory test results, and imaging studies.
