Imaging features of the initial chest high resolution CT scan in juvenile patient with coronavirus disease 2019

Abstract

The coronavirus disease 2019 (COVID-19) was confirmed by nucleic acid test in 15 juvenile patients aged 4-17 years in Hangzhou Xixi Hospital from January 24 to February 10, 2020. The clinical data and the initial chest high resolution CT (HRCT) findings were retrospectively analyzed.Among 15 cases, 8 patients with a mean age of (6.5±2.3) years (4-11 year) had normal HRCT manifestations (mild disease), while 7 patients with a mean age of (11.9±3.0) years (7-17 years) showed abnormal manifestations (moderate disease). In the 7 moderate cases the CT findings included local thickening of bronchial wall in 2 cases, single lesion in 1 case, bilateral pulmonary lesions in 4 cases. There were total 11 lesions, 6 of which were ground glass and slightly high-density nodules, 5 of which were speckled ground glass and 2 with a little consolidation. There were 10 subpleural lesions, including 7 in the lower lobe of the two lungs, and 1 non-subpleural lesion; the thickened local bronchioles were observed in 3 cases. None of them had hilum and mediastinal lymph node enlargement or pleural effusion. Key words: Coronavirus infection; Coronavirus disease 2019; Minors; Tomography, X-ray computed; Diagnosis
