Abstract
On fluorine-18-FDG PET imaging, bronchioloalveolar carcinomas usually have lower FDG uptake than expected for malignant tumors. Thus, bronchioloalveolar carcinoma can be a potential cause of false-negative findings of malignancy on FDG PET scans. When bronchioloalveolar carcinoma is suggested, FDG PET results should be interpreted in combination with high-resolution CT findings or biopsy. We report a case with known bronchioloalveolar carcinoma and a positive CT scan where the FDG PET imaging was negative in this patient.支氣管肺泡癌與其他惡性腫瘤相比很少在 氟-18-FDG正子攝影被發現，因此要診斷肺部的結節是否為支氣管肺泡癌，常需要藉 助於放射線或病理切片檢查。我們所提出的病例正是肺部的結節在 電腦斷層掃瞄被 發現，但在氟-18-FDG正子攝影卻沒有顯影，而後來 的病理切片報告證實為典型的支 氣管肺泡癌。
