Multifocal Mass-like Pulmonary Consolidation in a Patient with Community-Acquired Pneumonia Caused by Pseudomonas Aeruginosa
摘要
Pseudomonas aeruginosa (P. aeruginosa) is a less common pathogen causing community-acquired pneumonia. However, patients with chronic airway disease are vulnerable to P. aeruginosa infection. P. aeruginosa infection is associated with a poor quality of life, frequent exacerbation, and a high mortality rate in patients with bronchiectasis. Groundglass attenuation, peribronchial infiltration and consolidation, but not mass-like lesions, are the common radiographic features of P. aeruginosa pneumonia. Here, we reported a rare case of P. aeruginosa pneumonia with multifocal conglomerate mass-like consolidation. Ultrasound-guided transthoracic aspiration was performed to rule out malignancy, and pus was aspirated, which showed numerous inflammatory cells and yielded P. aeruginosa. The early diagnosis of P. aeruginosa pneumonia in this case helped in the initiation of appropriate antibiotic treatment and eliminated the need of an investigation for mass-like lesions. The mass-like lesions resolved after antibiotic use. In this case report, we reviewed the clinical presentations and radiographic patterns of P. aeruginosa pneumonia and the diagnostic value of sono-guided needle aspiration.
