We report an unusual case of left atrial auricular abscess which was successfully treated by surgical resection, treatment with antibiotics and mediastinal irrigation. A 9-year-old female patient with previous history of urinary tract infection was admitted because of persistent fever. Echocardiography and magnetic resonance imaging revealed massive pericardial effusion and a mass lesion at the left upper cardiac border. Pericardiocentesis isolated Staphylococcus aureus on culture. The patient underwent mass removal under cardiopulmonary bypass. The mass was located within the left atrial auricular wall with fibropurulent abscess formation inside. Postoperative mediastinal irrigation was performed. Pathologic examination of the mass showed organized thrombi with chronic fibrosing mural endocarditis. She discharged on the 21st postoperative day without complication.

The systemic lupus erythematosus(SLE) is a systemic inflammatory disease caused by autoimmune mechanism, involving blood cells, the kidney, the central nervous system, and etc. The heart is one of the frequently involved organs but it is rare as an initial manifestation. Therefore, early suspicion and accurate diagnosis followed by aggressive immunosuppressive therapy including corticosteroid is mandatory for heart-involved patients. We experienced a case of pericardial effusion as an initial manifestation of childhood SLE, which showed immediate response to corticosteroid.

In young adolescent girls, anorexia nervosa is a significant cause of weight loss, and hospital admissions among children and adolescents. Anorexia nervosa is a life-threatening disorder, with about one-third of deaths caused by cardiac complications. A high rate of pericardial effusion has been recently reported in patients with anorexia nervosa, although relatively few cases require pericardiocentesis. Here, we describe three patients with anorexia nervosa who were diagnosed with large pericardial effusions. To prevent cardiac tamponade, pericardiocentesis was performed in two girls.

Mediastinal teratoma is one of the most common lesions found in the anterior mediastinum, accounting for $8\sim13%$ of all mediastinal tumors. This tumor is incidentally detected by routine chest roentgengography, but pericardial perforation or pleural effusion occurs rarely. In our patient cardiac tamponade was developed due to anterior chest wall contusion, we confirmed the anterior mediastinal tumor. Vital signs were stabilized after the pericardiocentesis, and the patient underwent the tumor resection in the anterior mediastinum for a definite treatment. On histologic examination, the tumor revealed cystic structures composed of mature squamous epithelium, pilosebaceous glands, mature fat tissue, gastrointestinal mucosa, respiratory epithelium, and pancreatic tissues.
