Cardiac tamponade secondary to haemophilus pericarditis: a case report.

Pyogenic pericarditis is encountered uncommonly in clinical practice. The majority of cases of clinically apparent pericarditis are viral in origin. When bacterial infection of the pericardial space does occur the causative organism is usually Staphylococcus or Streptococcus species. Isolation of an haemophilus organism from the pericardial space in this condition is distinctly unusual. There are only 10 previously reported cases in the literature of pericarditis secondary to Haemophilus influenzae. This report describes the case of a 36-year-old woman who presented with haemophilus empyema and purulent pericarditis progressing to cardiac tamponade. There are isolated reports of successful treatment of pyogenic pericarditis with closed drainage and antibiotics. In the absence of clear evidence demonstrating the efficacy of this approach the authors favour open exploration of the pericardial space.
