摘要：

A 62-year-old patient with prostate adenocarcinoma underwent PET with radiolabeled choline (F-18-Fcholine) for pretreatment staging of a high-risk prostate cancer. Images showed a significant mediastinal lymph node uptake of F-18-Fcholine. Owing to the rarity of spread to supradiaphragmatic lymph nodes, a surgical removal was performed, revealing anthracosis and no malignant cells. Even if its specificity seems better than F-18-FDG, false positives have been reported and other pathologies couldmimic lymph node metastases. Consequently, histology should be performed so that the appropriate treatment can be initiated.
