A 4-year-old girl with COVID-19 pneumonia who presented with a low-grade fever. a The initial chest radiograph shows bilateral peribronchial thickening, predominantly in the right lower lung field. The findings are consistent with the indeterminate pattern of COVID-19 pneumonia. The severity scoring in this patient was calculated as the sum of the right lung scores and the left lung scores (total scores = 2 + 1 = 3). b On day 6 of admission, the radiographic evaluation reveals an almost complete resolution of the infiltrative lung involvement. The follow-up severity score in this patient was calculated as the sum of the right lung scores and the left lung scores (total scores = 1 + 0 = 1). COVID-19, coronavirus disease-19
