An electrocardiogram showed ST-segment elevation and PR-segment depression on multiple leads. A transthoracic echocardiogram showed normal left ventricular function and a large amount of pericardial effusion. Acute pericarditis was diagnosed, and anti-inflammatory drug therapy was initiated. Due to the lack of improvement in the symptoms, pericardiocentesis was performed on Day 8 and revealed about 800\u2009cc of the bloody fluid. Parvimonas micra was detected in a culture of the pericardial effusion and blood. Although intravenous antibiotic therapy was initiated for purulent pericarditis, his fever persisted. Computed tomography of the chest performed on Day 14 showed an abscess cavity in the pericardial space around the right atrium (RA). Furthermore, transoesophageal echocardiography revealed vegetation in the RA. Emergency surgery confirmed the presence of vegetation and minor perforation of the RA with communication to the abscess cavity. After surgical therapy, the patient clinically improved and was discharged on Day 51.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>In cases of acute pericarditis, purulent pericarditis should be considered if clinical improvement is not observed after initial treatment with anti-inflammatory drugs.
