Int J Infect Dis. 2013 Nov;17(11):e1064-6. doi: 10.1016/j.ijid.2013.03.013. Epub 2013 Apr 30.

Abstract

We report a rare case of mycotic pulmonary artery pseudoaneurysm (PAP) secondary to a lung abscess due to Streptococcus constellatus. PAP was confirmed by the pathological findings of the pseudoaneurysm, the presence of bacteria, and the microbiological analysis. PAP is uncommon, but it is important to recognize this condition because PAP can lead to fatal hemoptysis.

Keywords: Hemoptysis; Pulmonary artery pseudoaneurysm; Streptococcus constellatus.
