摘要: A 76-year-old man presented with shortness of breath. Computed tomography revealed ground-glass opacity and interlobular thickening in the right lower lobe. Blood examination showed elevated levels white blood cell count lymphocytes. Bone marrow aspiration low-grade follicular lymphoma. Histopathological surgical lung biopsy from lobe demonstrated usual interstitial pneumonia scattered aggregation lymphocytes poorly formed non-necrotizing granuloma. An 18F-fluorodeoxyglucose positron emission tomography-computed (18F-FDG PET-CT) did not show intense uptake areas other than We concluded that granuloma was presumed to be a sarcoid reaction associated bone lymphoma, 18F-FDG might have been due reaction. Immunohistochemistry or genetic examinations are important even if on PET-CT seems false-positive because possibility
