- An 83-year-old man was referred with a right lung mass on
dynamic chest computed tomography (CT). F-18 fluoro-deoxy-glucose
positron emission tomography (FDG PET)/CT showed intense FDG uptake
in the right lung mass and bilateral hypermetabolic mediastinal lymph nodes.
CT-guided biopsy of the right lung mass revealed metastatic adenocarcinoma
from the colon, but a colon cancer lesion was not detected by dynamic
abdominal CT and colonoscopy.
Key Words: colorectal cancer, pulmonary metastasis, FDG-PET/CT,
