Key result
Influenza B infection can rarely cause acute pericarditis and cardiac tamponade, requiring emergent pericardiocentesis for successful management.
Why the study?
Extra-pulmonary manifestations of influenza infection are increasingly recognized, but pericardial disease related to influenza B infection is very rare.
Case Report (n=1)
No
Influenza B infection, though typically milder than Influenza A, can rarely cause severe acute pericarditis and cardiac tamponade requiring emergent pericardiocentesis.
Influenza B may cause pericarditis with tamponade; leaves open the true incidence and need for cardiac evaluation in severe cases.
Every year, Influenza infection contributes to significant morbidity and mortality carrying a huge economic burden. Extra-pulmonary manifestations are increasingly being recognized. We present a 29-year-old woman with acute pericarditis and cardiac tamponade requiring emergent pericardiocentesis secondary to Influenza B infection. Although very rare in relation to Influenza B infection, the pericardial disease can occur during the acute infection or as a post-viral syndrome. Considering pericardial disease in patients with chest pain and any viral infection may facilitate timely diagnosis and prevent unnecessary life-threatening complications.

Schroff et al. (2021) conducted a case report in Cardiac tamponade secondary to Influenza B infection (n=1). Influenza B infection was evaluated on Development of cardiac tamponade. Influenza B infection can rarely cause acute pericarditis and cardiac tamponade, requiring emergent pericardiocentesis for successful management.
