This study was conducted to evaluate various HRCT (High Resolution Computed Tomography) chest findings in COVID-19 patients of young, middle and old age groups and to determine the association of findings with age. Methods This was a hospital-based cross-sectional study conducted among 78 proven RTPCR positive patients who underwent HRCT chest in age groups of 18 and above at the Department of Radiology, Sagar Hospitals, Bangalore, from June 2020 to June 2021 after obtaining clearance from the institutional ethics committee and written informed consent from the study participants. Results On HRCT chest, the two most predominant types of lesions in the young age group were pure GGO and mixed GGO with interlobular thickening; in the middle-aged group, mixed GGO with airspace opacification; and in the older age group, mixed GGO with airspace opacification and mixed GGO with complete consolidation. With respect to the number of lesions, they were few in the younger age group and extensive in the middle and older age groups.
