In brief
Retrospective study of 84 pediatric patients identifies CT features that predict need for lung resection in complicated pneumonia. Multiple cavities ≥3cm combined with lung abscess are the strongest predictors, with 80% of resection patients showing two or more high-risk features on initial imaging.

Abstract
Purpose
To investigate computed tomography (CT) features which predict lung resection in children with complicated community-acquired pneumonia.
Methods
A retrospective study of CT findings of patients with complicated pneumonia treated between January 2010 and December 2019. Fisher's exact test and ROC curves were used for statistical analysis.
Results
The study cohort consisted of 84 patients who underwent chest CT for complicated pneumonia. Lung resection was performed in 36 patients, 3 patients were treated by lung decortication, 45 patients were cured conservatively. Seven CT features were found statistically significant among the patients who underwent lung resection. 80.5% of patients from the resection group had two or more of these features on the initial CT scan, 64% had three or more. According to ROC analysis, simultaneous occurrence of multiple cavities equal to or greater than 3 cm and lung abscess predicted a pulmonary resection.
Conclusion
The combination of CT features which clearly predict lung resection are the simultaneous occurrence of multiple cavities ≥ 3 cm and lung abscess. The most common triple combination of CT signs in the resected group of patients were multiple cavities ≥ 3 cm, consolidation of lung tissue and pleural effusion < 3 cm.
