BACKGROUND: Recently, the World Health Organization has declared the coronavirus
disease 2019 (COVID-19) outbreak a public health emergency of international
concern. So far, however, limited data are available for children. Therefore, we
aimed to investigate the clinical and chest CT imaging characteristics of
COVID-19 in preschool children. METHODS: From January 26, 2020 to February 20,
2020, the clinical and initial chest CT imaging data of eight preschool children
with laboratory-confirmed COVID-19 from two hospitals were retrospectively
collected. The chest CT imaging characteristics, including the distribution,
shape, and density of lesions, and the pleural effusion, pleural changes, and
enlarged lymph nodes were evaluated. RESULTS: Two cases (25%) were classified as
mild type, and they showed no obvious abnormal CT findings or minimal pleural
thickening on the right side. Five cases (62.5%) were classified as moderate
type. Among these patients, one case showed consolidation located in the
subpleural region of the right upper lobe, with thickening in the adjacent
pleura; one case showed multiple consolidation and ground-glass opacities with
blurry margins; one case displayed bronchial pneumonia-like changes in the left
upper lobe; and two cases displayed asthmatic bronchitis-like changes. One case
(12.5%) was classified as critical type and showed bronchial pneumonia-like
changes in the bilateral lungs, presenting blurred and messy bilateral lung
markings and multiple patchy shadows scattered along the lung markings with
blurry margins. CONCLUSIONS: The chest CT findings of COVID-19 in preschool
children are atypical and various. Accurate diagnosis requires a comprehensive
evaluation of epidemiological, clinical, laboratory and CT imaging data.
