Abstract
Background: COVID-19 caused by SARS CoV-2 involves respiratory system leading to respiratory failure and Acute Respiratory Distress Syndrome (ARDS) in critical patients. Several chest imaging features have been reported in patients with COVID-19 ranging from focal to diffuse lung opacities. There is no data from Saudi Arabia on the chest imaging findings in these patients. Material and Methods: CT chest data of 29 patients who were admitted with confirmed diagnosis of COVID-19 by real-time reverse transcriptase polymerase chain reaction (RT-PCR) was reviewed. Radiology abnormality was categorized based upon pattern and distribution. Clinical and laboratory data of patients were collected by reviewing the electronic medical record. Patients were divided into mild and severe group based on clinical assessment and laboratory criteria. Radiology changes were compared with disease severity. Results: Median (Q1, Q3) age was 58 (41,70) years and median (Q1, Q3) time from symptom onset to CT scan was 6.5 (3.0, 9.75) days. Bilateral ground glass opacities were the most common CT scan feature in patients with COVID-19 (76%). Opacities were dominant in the lower zone (72%) and frequently distributed peripherally (48%). Severe disease was most likely to have bilateral opacities compared with mild (p = 0.001) and it was correlated with rise of inflammatory markers, Ferritin (p=0.014) and C-reactive protein (p=0.0003). Conclusion: Most patients with COVID-19 who have abnormal CT scan of chest show ground glass opacities. Bilateral opacities are more common in severe disease and is correlated with elevated inflammatory markers.
