Abstract

The information about imaging findings of COVID-19 disease on HRCT is evolving every day and is widely distributed across numerous publications Main objectives of our study were to identify important imaging manifestations, atypical manifestations and distribution of the lesions in the patients with COVID-19 to help the fellow radiologists and physicians globally so that it ensures proper clinical management. Our study is a multi-centric retrospective study done on a total of 81 COVID-19 affected symptomatic patients. HRCT was done on all the patients and detailed history of the patient’s symptoms and characteristics are recorded. The most common symptoms observed were fever, cough and dyspnoea. On HRCT the most common finding observed was ground glass opacities, seen in 28 cases which comprise 35% of the study population. Consolidation alone and combined consolidation & ground glass opacities were observed in 12(15%) and 17(21.1%) cases respectively. Among other ancillary findings air-bronchogram, sub-pleural lines and fibrotic opacities were most commonly observed. Most of the cases showed peripheral or sub-pleural involvement and both lower lobes are the most affected regions of the lungs. In our study we found that ground glass opacities are the most common findings in the lungs of COVID-19 patients. The sub-pleural or peripheral lung fields and the lower lobes are the most affected regions of the lungs. Most of the COVID-19 cases show region s of sub-pleural fibrosis as evidenced by presence of sub-pleural lines
