title: Pseudomonas aeruginosa bronchopulmonary infection in patients with advanced human immunodeficiency virus disease.
abstract: Pseudomonas aeruginosa is increasingly reported as a respiratory pathogen in patients with advanced human immunodeficiency virus (HIV) disease. We retrospectively reviewed the chest radiographic appearances of 29 HIV-infected adults with bronchopulmonary infection in whom Pseudomonas aeruginosa was the sole respiratory pathogen isolated. The commonest radiographic abnormality was a diffuse reticular (11 patients) or reticulonodular (9 patients) infiltrate in the pulmonary interstitium. Alveolar opacification was seen in seven patients. Cavitation was rare (2 patients), as was ground-glass opacification (2 patients). Five patients had pleural effusions. No patient had mediastinal or hilar lymphadenopathy. Normal chest radiographs were seen in eight patients. Although the radiographic appearances of Pseudomonas bronchopulmonary infection in HIV-infected patients are non-specific, an interstitial infiltrate is a common finding. Pseudomonas aeruginosa should be considered along with the commoner pathogen Pneumocystis carinii in the differential diagnosis of an interstitial infiltrate in this group of patients.
