Staphylococcus aureus endocarditis complicated by bilateral pneumothorax.

Staphylococcus aureus is the most common cause of endocarditis in intravenous drug users. The organism gains access by intravenous injection or from the direct invasion of skin at injection sites. Known for its aggressiveness, the right sided endocarditis that ensues can lead to complications such as pulmonary abscesses and even death. We report the unusual case of an intravenous drug abuser, who following the occurrence of extensive pulmonary abscesses, developed bilateral pneumothoraces within a few days.
