Although Coronavirus Disease 2019 (COVID-19) affects patients from all age groups, clinical and radiological features of COVID- 19 have been mainly described in adults.

Objective

To characterize and compare the initial clinical and imaging features of COVID-19 in pediatric and adult patients undergoing chest computed tomography (CT).

A total of 61 patients, consisting of 47 adults (18 years old or older) and 14 pediatric patients (younger than 18 years old) with laboratory-confirmed COVID-19 by real-time reverse transcriptase polymerase chain reaction (RT-PCR) between January 25, 2020 and February 15, 2020 were enrolled in this study.

All patients underwent chest CT within 3 days after the initial RT-PCR. The clinical presentation, serum markers, and CT findings were assessed and compared between the adult and pediatric patients.
