摘要


肺部類癌瘤與其他惡性腫瘤相比很少在氟-18-去氧葡萄糖正子攝影被發現,因此要診斷肺部的結節是否為相對比較良性的肺部類癌瘤,常需要藉助於放射線或病理切片檢查。雖然類癌瘤不易在氟去氧葡萄糖正子攝影被發現,但是我們所提出的病例卻是正子攝影有顯影的肺部類癌瘤,而後來的病理切片報告證實為較惡性的非典型類癌瘤。

On fluorine-18-FDG PET imaging, pulmonary carcinoid tumors usually have lower FDG uptake than expected for malignant tumors. Biopsy or close radiologic follow-up is therefore recommended for solitary pulmonary nodules that are clinically suspected to be carcinoid tumors and that do not show significantly increased metabolic activity on FDG PET images. We report a case where the FDG PET imaging was positive in this patient with known primary pulmonary carcinoid tumor. This tumor mass is classified as an atypical(moremalignant)carcinoid tumor at pathology.
