Answer

Tuberculosis accounts for 4% of cases and should be considered in all instances of pericarditis without a rapid course, especially in high-risk groups, such as elderly patients in nursing homes and those with acquired immunodeficiency syndrome (AIDS). [15] Approximately 50% of affected patients develop constrictive pericarditis. On rare occasion, acute purulent pericarditis is caused by coinfection with Mycobacterium tuberculosis and S aureus, and this may be the first manifestation of infection with human immunodeficiency virus (HIV).
