ABSTRACT
A 78-year-old woman was referred to our hospital with symptoms of leg edema and dyspnea. Lung cancer of the right middle lobe, with pleural and pericardial dissemination were suspected on FDG-PET. Pericardial thickening impaired venous return, which led to hemodynamically unstable tachycardia. Steroid medication used for symptom palliation resulted in the formation of an abscess of the pericardial nodules and left empyema. Actinomyces israelii was identified on pleural effusion. Pericardial abscesses, empyema, and hemodynamic condition improved with intravenous ampicillin/sulbactam. Thoracic actinomycosis had mimicked lung cancer.
