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.
