WSI22-75-Case-1
A 54-year-old man with a primary diagnosis of rectal carcinoma was found to have multiple lung lesions and a FDG avid (SUV 3.8) nodule in the anterior mediastinum during work-up. Lung lesions were proven to be metastases from the rectal primary by biopsy. However, it was felt that the anterior mediastinal nodule was atypical for a metastasis from the rectal primary; thus, he underwent the resection of the mediastinal nodule.
