Imaging:
All patients underwent CXR during hospitalization. The incidence of consolidation on CXR was similar in the CCAP and CAP groups. However, effusion was more common in CCAP patients than in CAP patients (p<0.001). CCAP patients often present with atelectasis (p=0.027) and pneumothorax (p=0.01). Simple pleural effusion was observed on CXR, and three (3.22%) CAP patients underwent thoracic USG. Moreover, 13 (72.2%) CCAP patients with suspicious CXR and other findings upon admission underwent CT scan because sufficient information could not be obtained via thoracic USG. Then, 3 (3.22%) of 93 CAP patients were followed-up for persistent fever and CCAP.
Of 18 patients diagnosed with CCAP, 8 (44.43%) presented with PPE, 7 (38.88%) with EMP, 2 (11.1%) with NP, and 1 (5.55%) with LA. One patient who was followed-up due to CCAP presented with Morgagni hernia on CT scan, and surgical consultation was then requested. One patient with NP had pneumatocele. In addition, another patient who was followed-up for LA had BPF (Table-3).
