  • Title: Asymmetric pulmonary hypermetabolism on 18F-FDG PET/CT caused by pulmonary embolism.
    Author: Caekebeke E, Deroose CM, Verhamme P, Coolen J, Gheysens O.
    Journal: Clin Nucl Med; 2015 Apr; 40(4):338-9. PubMed ID: 25608154.
    Abstract:
    We present a case of diffuse and moderately increased 18F-FDG uptake in the entire left lung on 18F-FDG PET without any morphological parenchymal abnormalities in a patient with recent history of esophageal adenocarcinoma treated by minimal invasive surgery and adjuvant chemotherapy. Contrast-enhanced CT revealed a large embolism in the left pulmonary artery with near total occlusion. In the absence of parenchymal lesions, the increased 18F-FDG uptake is most likely an inflammatory response to a recent ischemic insult. This case illustrates that asymmetric lung hypermetabolism in the absence of parenchymal disease can be caused by a central pulmonary embolism.
