Abstract
Pulmonary sarcomatoid carcinoma (PSC) is a rare and highly aggressive form of non-small cell lung cancer. Rectal metastasis of PSC is an extremely rare condition. We herein report a rare case of PSC accompanied by rectal metastasis detected by 18F-FDG PET/CT. This case highlights the diagnostic value of 18F-FDG PET/CT in detecting uncommon metastatic sites in PSC.
