Pseudomonal pericarditis complicating cystic fibrosis.

Patients with advanced cystic fibrosis typically have chronic bacterial infection of the upper and lower respiratory tracts, but rarely develop extrapulmonary sites of infection. We report a case of purulent pericarditis due to Pseudomonas aeruginosa in a patient with cystic fibrosis and no other risk factors for pericarditis. This is a previously unreported complication in cystic fibrosis prior to lung transplantation.
