Echocardiography showed a large pericardial effusion and pericardiocentesis yielded purulent fluid. Streptococcus equi was isolated. Computed tomography confirmed an oesophagopericardial fistula. The patient underwent percutaneous drainage, broad-spectrum antimicrobial therapy, and endoscopic stent placement. Despite initial improvement, he developed effusive\u2013constrictive physiology and later refractory septic shock, leading to death.<\/jats:p>\n                  <\/jats:sec>\n
