Imaging and clinical manifestations of viral pneumonia are protean and not reliably predictive of its origin. All patients with neutropenic fever and normal findings at chest radiography should undergo thin-section computed tomography to determine whether parenchyma abnormalities are present. Although the radiologic manifestations of viral pneumonia are nonspecific and difficult to differentiate from those of other infections, it is important to consider viral infection when confronted with a rapidly progressive pneumonia in patients with risk factors for infection. Although definitive diagnosis cannot be made on the basis of imaging features alone, the use of a combination of clinical and radiographic findings can substantially improve the accuracy of diagnosis in this disease.
病毒性肺炎的影像学和临床表现多种多样，无法可靠预测其病因。所有中性粒细胞减少症发热且胸部 X 线摄影正常的患者均应进行薄层 CT 检查，以确定是否存在实质异常。虽然病毒性肺炎的放射学表现是非特异性的，且难以与其他感染相区分，但在存在感染危险因素的患者中出现快速进展性肺炎时，应考虑病毒感染。虽然仅凭影像学特征不能明确诊断，但结合临床和影像学表现可显著提高该疾病的诊断准确性。
