52-year male with positive COVID-19 virus. Initial chest X-ray (a) showed air space consolidation opacities at the periphery of the mid and lower zones of the right lung and small patch at the left lower lung zone (arrows) with TSS 3 (2 on the right side and 1 on the left side). On the 3rd day (b), air space consolidation opacities (arrows) increased on the left side and TSS became 4. On the 5th day (c), 8th day (d), and 12th day (e), air space consolidation opacities (arrows) were almost the same but with increased reticular interstitial thickening seen on d and e
