The most common symptoms of COVID-19 include fever, cough, dyspnea, fatigue, and myalgia, less common symptoms are sputum, hemoptysis, headache, and gastrointestinal symptoms. Six coronaviruses are identified, four of which cause mild common cold symptoms, and two strains were responsible for Severe Acute Respiratory Syndrome (SARS) that began in southern China in 2003 and Middle East Respiratory Syndrome (MERS) that originated in Saudi Arabia in 2012. The coronaviruses are widely distributed among humans and mammals. The viruses have characteristic morphology under the electron microscope with presence of viral spike peplomers arising from the viral envelope giving a crown appearance. Ĭoronaviruses are enveloped, positive-sense, single strand, non-segmented, and ribonucleic acid viruses that belong to the coronaviridae family. A virus was identified and isolated from the epithelial cells of the respiratory system of infected individuals and was named as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and the outbreak was named coronavirus disease (COVID-19). In January 2020, the World Health Organization (WHO) declared it a pandemic. The illness rapidly spread in China and in many other countries. Chest x-ray can be used in diagnosis and follow up in patients with COVID-19 pneumonia.Īn outbreak of severe cases of pneumonia from an unidentified origin emerged in Wuhan, China in December 31, 2019. ConclusionĪlmost half of patients with COVID-19 have abnormal chest x-ray findings with peripheral GGO affecting the lower lobes being the most common finding. The majority (12/13, 92.3%) of patients with abnormal chest x-rays were symptomatic ( P = 0.005). There was increase in the frequency of normal chest x-rays from 9% at days 6–11 up to 33% after 18 days indicating a healing phase. The consolidations regressed into GGO towards the later phase of the illness at 12–17 days (GGO 80%, consolidations 10%). In the course of illness, the GGO progressed into consolidations peaking around 6–11 days (GGO 70%, consolidations 30%). The most common finding on chest x-rays was peripheral ground glass opacities (GGO) affecting the lower lobes. A total of 190 chest x-rays were obtained for the 88 patients with a total of 59/190 (31%) abnormal chest x-rays. 48/88 (45%) were symptomatic, only 13/88 (45.5%) showed abnormal chest x-ray findings. ResultsĪ total of 88 patients (50 (56.8%) females and 38 (43.2%) males) were admitted to the hospital with confirmed COVID-19. Radiographic findings were correlated with the course of the illness and patients’ symptoms. Patients’ demographics, clinical characteristics, and chest x-ray findings were reported. Methodsįrom March 15 to Appatients with positive reverse transcription polymerase chain reaction (RT-PCR) for COVID-19 were retrospectively studied. The study aims at describing the chest x-ray findings and temporal radiographic changes in COVID-19 patients. Chest x-ray can be used in diagnosis and follow up in patients with COVID-19 pneumonia. Chest CT scan and chest x-rays show characteristic radiographic findings in patients with COVID-19 pneumonia.
