Introduction: HRCT Chest is currently considered as a particularly important tool for diagnosis as well as follow-up for evaluation of lung parenchyma and adjacent structures in COVID-19 patients. The purpose of this study is to assess the radiological findings in COVID-19 patients and evaluate the pattern of involvement as well as complications in various age-groups in a subset of Puducherry population. Methods: This is a retrospective study done on 40 patients who were RT-PCR positive for COVID-19 and were referred for HRCT Chest to the department of radiodiagnosis of Sri Lakshmi Narayana Institute of Medical Sciences Medical College and Hospital, during the period of June 2020 to August 2020. All the patients who were included in this study were RT-PCR positive for COVID-19. Results: The most important and frequent findings seen in the study were ground-glass opacities seen in 38 patients (95%) followed by consolidation which was seen in 23 patients (57.5%). The other significant findings were crazy-paving, sub-pleural bands, atelectasis, traction bronchiectasis and adjacent vascular dilatation. A normal non dilated pulmonary artery may be seen in the presence of Pulmonary embolism, especially if unilateral, and further imaging such as CT Pulmonary Angio should be suggested in cases of clinical suspicion. Conclusion: CT is sensitive for the confirmation of the diagnosis as well as in interpretation of the lung parenchymal involvement to predict the requirement of further follow-up. Atypical findings such as sub pleural bands, atelectasis, cysts, and halo sign may be seen without the presence of typical imaging features in COVID positive patients.
