ABSTRACT

Background: After its emergence in Wuhan, China COVID-19 (Coronavirus 2019 disease) has spread across the world at the end of 2019. It has become important to study and understand the type and pattern involvement of lung in COVID – 19 to help diagnose and manage this disease. Aim: To study and describe the spectrum of High resolution computed Tomography (HRCT) chest findings in coronavirus disease-19 (COVID-19) infected patients at our institute. Methods: 111 RT-PCR (reverse transcriptase polymerase chain reaction) positive or Rapid Antigen Test (RAT) positive patients who underwent HRCT chest were included in this observational analysis. The prevalence, distribution, extent, and kind of abnormal lung findings were investigated. Results: Out of the 111 study subjects, 76 (67.87 %) male patients and 36 (32.14 %) female patients. Lung parenchymal abnormalities were found in 78.3%. Rest of the RT-PCR or RT positive cases had a normal chest CT. The most common findings in the lung parenchymal abnormalities on CT were major peripheral and posterior distributions of ground-glass opacities. Ground glass opacities (GGO) were noted in 87 (i.e. 100 %) cases. Ground glass opacities were purely observed in 32 % patients. Crazy paving patterns were noted in 20.67 % patients. In 47.1 % patients, GGO with consolidation was also noted. Conclusion: Patients who tested positive for RT-PCR or RAT were included in this cohort research had a predominantly bilateral and peripheral distribution of GGOs which were typical findings in 78.3 % of patients whereas normal chest CT was seen in the remaining patients.
