摘要
A 76-year-old man with biopsy-proven metastatic papillary thyroid cancer in a mediastinal nodule status post total thyroidectomy is on surveillance. The patient also had prostate cancer and received prostatectomy and androgen deprivation treatment. An F-18-fluciclovine PET revealed avid lesions in the mediastinal nodule and a sclerotic focus at L5 with concurrent prostate-specific antigen level of 0.4 ng/mL. The L5 lesion was later biopsied and confirmed as metastasis from prostate cancer. A Ga-68-PSMA-11 PET 2 months later showed avid radiotracer uptake within L5 metastasis but not the mediastinal nodule. The patient received radiation therapy to the L5 lesion and responded well.
