False Positive 18F-FDG Uptake in Mediastinal Lymph Nodes for a Patient with Pulmonary Adenocarcinoma: A Case Report
氟－18去氧葡萄糖在肺腺癌患者縱膈腔淋巴結之偽陽性攝取：病例報告
摘要
氟－18去氧葡萄糖正子斷層造影(18F-FDG PET)已被廣泛運用於非小細胞肺癌的分期。我們在此報告一位右肺中葉腺癌的病人，她的氟－18FDG PET檢查顯示眾多膈腔淋巴結有氟－18-FDG高度攝取。這個73歲的家庭主婦後來接受了右肺中葉切除和中膈腔淋巴結廣泛摘除。取出所有42個淋巴結病理切均顯示為有淋巴反應增生的碳末沉積症。這個病例顯示非小細肺癌患者有氟－18－FDG中膈腔淋巴結，未必是惡性病灶。
並列摘要
18F-FDG PET has been widely used for staging nonsmall cell lung cancer. We report herein a case of rightmiddle- lobe adenocarcinoma with multiple 18F-FDG-avid lymph nodes in mediastinum. The patient is a 73-yearold housewife who has received right middle lobe lobectomy and extensive dissection of mediastinal lymph nodes. Pathologic examination of all the fortytwo lymph nodes dissected reveals anthracosis with reactive lymphoid hyperplasia. This example illustrates that 18F-FDG uptake of mediastinal lymph nodes in patients with non-small cell lung cancer may not be caused by malignancy.
