Objectives: We evaluated the efficacy of fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET) in the detection of extrathoracic malignancies in patients with suspected lung cancer. Patients: A total of 79 patients with lung abnormal shadows who underwent FDG-PET from 1997 to July 2000 were retrospectively evaluated. In 8 cases (approximately 10%) extrathoracic malignancies were recognized. Results: The 8 cases consisted of 1 gastric cancer, 2 colon cancers, 2 thyroid cancers, 1 laryngeal cancer, 1 pancreas cancer and 1 splenic malignant lymphoma. In all cases, FDG-PET images successfully detected all lesions but 67Ga-planar images did not. Conclusion: Our results suggested that multiple malignancies are not rare and FDG-PET is valuable in the diagnosis of such diseases.
