(B) Chest computed tomography (CT) on admission showed non‐segmented ground glass opacities only in the peripheral areas of both lower lobes with no bronchial wall thickening. (C) Chest X‐ray (Anterior–Posterior view) on day 8 from the onset of coronavirus disease‐2019 (COVID‐19) showed bilateral infiltrative shadows mainly in peripheral lung fields. (D) Chest CT on day 20 from the onset of COVID‐19 showed bilateral ground‐glass shadows with bronchial wall thickening. No pleural effusions and cardiac hypertrophy were observed.
