Introduction
Purulent bacterial pericarditis is uncommon, accounting for <1% of cases1. It is generally manifested as a serious febrile disease, which should be managed aggressively with urgent pericardiocentesis, as death is inevitable if it remains untreated1. Giant “mycotic” coronary artery aneurysms (over 2 cm in diameter)2 are rare but potentially fatal infectious conditions usually associated with infectious endocarditis or bacteremia, particularly in immune-compromised patients3,4. The term “mycotic” is a misnomer but is commonly used to describe an infected coronary artery aneurysm (ICAA) regardless of the type of infection4. Herein, we present a case of a giant infected aneurysm of the right coronary artery (RCA) complicated with purulent pericarditis in an 83-year-old male patient.
