Chest computed tomography (CT) is the most accurate test for assessing parenchymal anomalies. Radiographic findings indicative of pneumonia may be observed even when no anomalies are observed on chest X-rays [53] . Chest CT is more accurate than chest X-rays in the diagnosis of complications such as pleuritis and pulmonary necrosis [54, 55] and in the exclusive diagnosis and differential diagnosis of non-infectious lung diseases such as atelectasis, pulmonary infarction, tumor, and interstitial lung disease that may exhibit similar characteristics as those of pneumonia on X-rays [56] [57] [58] [59] . Since CT findings can vary depending on the identity of the causative bacteria of pneumonia, CT is useful for identifying causative bacteria [56, [60] [61] [62] . CT findings suggestive of mycobacteria that must be differentiated from common pneumonia, and of fungal lung infection can also be obtained [56, 63, 64] .
