Résumé : Case report: a 63-year old man, followed for a metastatic cardia cancer, develop a pericardial effusion with sign of pre-tamponade. A CT scanner suggests the presence of a gastroesophageal- pericardial fistula. A surgical drainage brings a purulent fluid, infected by a polymicrobial flora. Despite early antibiotics with vancomycin and piperacillin-tazobactam, the patient dies five days after the drainage. Discussion: purulent pericarditis associated with gastrointestinal neoplasia may be due to sepsis or a proximity invasion . The diagnosis is based on ultrasound and pericardiocentesis. The most commonly involved organism is Streptococcus pneumoniae. The treatment involves intravenous ant ibiotics, pericardial drainage and intrapericardial instillation of antibiotics. The mortality rate remains high, especially in cases associated with gastrointestinal neoplasia.
