Purulent pericarditis presenting as an extracardiac mass in a patient with untreated diabetes.
A 50-year-old man with symptoms of bi-ventricular heart failure was transferred to our hospital with a diagnosis of extracardiac tumor. He had a 10 year history of untreated diabetes. Chest computed tomography (CT) revealed an extracardiac mass in the right atrio-ventricular groove. Cardiac catheterization revealed an elevated mean right atrial pressure of 18 mmHg, mean pulmonary wedge pressure of 16 mmHg, and the right ventricular pressure curve demonstrated typical dips and plateaus. At surgery, there was severe adhesion between the pericardium and epicardium, and the pericardium was severely thickened and contained turbid pus. In the left thoracic cavity, there was large amount of pleural effusion and pus. Therefore, the patient was diagnosed with purulent pericarditis caused by left empyema. The thickened pericardium at the anterior portion of the heart was resected, however resection of the remaining portion was abandoned because the adhesion was so tight. After surgery, the patient underwent irrigation of the heart and left thoracic cavity by 1% povidone iodine solution and 0.5 mg/ml of imipenem for 7 days. Bacteriologic culture of the pus from the pericardium revealed anaerobic gram negative bacteria. After 4 months of antibiotics infusion, his C reactive protein became negative and the patient was subsequently discharged from our hospital.
