Key result
Austrian syndrome with purulent pneumococcal pericarditis and normotensive tamponade proves fatal despite aggressive management.
Why the study?
Austrian syndrome is a rare manifestation of invasive Streptococcus pneumoniae infection, and purulent pneumococcal pericarditis causing cardiac tamponade is an exceptionally uncommon, life-threatening complication.
Case Report (n=1)
Cardiac tamponade from purulent pneumococcal pericarditis can present with preserved blood pressure, requiring high clinical suspicion and prompt echocardiography.
Raises awareness of fatal purulent pericarditis in Austrian syndrome; case report leaves open optimal management strategies.
BACKGROUND: Austrian syndrome is a rare manifestation of invasive Streptococcus pneumoniae infection. Purulent pneumococcal pericarditis causing cardiac tamponade is an exceptionally uncommon but life-threatening complication. CASE SUMMARY: A 63-year-old unhoused woman presented with altered mental status and respiratory failure. Despite preserved blood pressure, electrocardiography demonstrated electrical alternans, and point-of-care echocardiography revealed cardiac tamponade. Pericardiocentesis yielded purulent fluid growing S pneumoniae. Systemic emboli and echocardiographic findings were consistent with Austrian syndrome complicated by purulent pericarditis and cardiac tamponade. Despite medical and surgical management, the patient developed refractory shock and died. DISCUSSION: Purulent pneumococcal pericarditis may present with tamponade despite normotension or hypertension. Early recognition and prompt drainage are critical. TAKE-HOME MESSAGES: Cardiac tamponade may occur despite preserved blood pressure. Electrical alternans and point-of-care echocardiography are key diagnostic clues. Purulent pericarditis often requires surgical drainage and carries high mortality.

Delgadillo et al. (2026) conducted a case report in Austrian syndrome with purulent pneumococcal pericarditis and cardiac tamponade (n=1). Medical and surgical management (including pericardiocentesis) was evaluated on Clinical outcome. A 63-year-old woman with Austrian syndrome developed purulent pneumococcal pericarditis and normotensive cardiac tamponade, ultimately dying from refractory shock despite medical and surgical management.
