Abstract
Objectives; To compare the pulmonary thin-section CT findings in patients with seasonal influenza virus pneumonia with Streptococcus pneumoniae pneumonia. Methods; The study group included 30 patients (20 male, 10 female; age range 20-91 years, mean age 55.9) with seasonal influenza virus pneumonia, and 71 patients (47 male, 24 female; age range 27-92 years, mean age 67.5) with S. pneumoniae pneumonia. Results; The proportion of community-acquired infection was significantly higher in patients with influenza virus pneumonia than with S. pneumoniae pneumonia (P = 0.001). CT findings of ground-glass attenuation (P = 0.012) and crazy-paving appearance (P = 0.03) were significantly more frequent in patients with influenza virus pneumonia than with S. pneumoniae pneumonia. Conversely, consolidation (P < 0.001), mucoid impaction (P < 0.001), centrilobular nodules (P = 0.04) and pleural effusion (P = 0.003) were significantly more frequent in patients with S. pneumoniae pneumonia than those with influenza virus pneumonia. Conclusions; Pulmonary thin-section CT findings such as consolidation and mucoid impaction may be useful in distinguishing between seasonal influenza virus pneumonia and S. pneumoniae pneumonia. Advances in knowledge; 1. Distinguishing seasonal influenza virus pneumonia with Streptococcus pneumonia pneumonia is important. 2. The CT findings of GGA and crazy-paving appearance were more frequently found in patients with influenza virus pneumonia than for patients with Streptococcus pneumoniae pneumonia, while consolidation, mucoid impaction, centrilobular nodules and pleural effusion were more frequently found in patients with Streptococcus pneumoniae pneumonia.
