Abstract
OBJECTIVES: To describe radiographic imaging findings and disease course in admitted Coronavirus disease 2019 (COVID-19) patients. METHODS: This retrospective study was carried in the Radiology Department, King Fahad Military Medical Complex, Dhahran between March to August 2020 (6 months). All laboratory confirmed COVID-19 admitted cases were evaluated for their symptoms, duration of hospital stays (in a ward or intensive care unit [ICU]), and imaging findings (ground-glass opacity [GGO], air-space shadowing/consolidation, and others such as atelectasis, reticulation, peribronchovascular thickening, lymphadenopathy and pleural effusion) on chest radiograph (CXR) and computed tomography (CT) studies. Cavitation, nodularity, bronchiectasis, and embolism detected on CT scans were considered as complications. Disease course in terms of recovery (radiographic regression or resolution of findings), worsening (shifting from ward to ICU), and unfavorable outcome (persistent ICU stay or death) were recorded. Imaging findings were interpreted by 2 experienced radiologists and consensus reporting was made. Chi-square test was used to determine association. Results: Out of 106 patients, majority were males (n=82, 77.4%). Forty-six patients (43.3%) had abnormal imaging with mostly peripheral GGO (56.5%), followed by consolidations (34.7%), and others (26%). Complications were detected in 6 ICU patients. All patients with unfavorable outcomes were above 60 years having comorbidities or complications (p less than 0.0005). Fatality rate was calculated as 2.8. Conclusion: Coronavirus disease 2019 is seen mostly affecting males, with peripheral opacities as common imaging findings. Elderly patients with co-morbidities may show unfavorable outcomes.
