Background: Coronavirus disease 2019 (COVID-19) has since December 2019 become a problem of global concern . Due to the virus' novelty and high infectivity, early diagnosis is key to curtailing spread . The knowledge and identification of chest Computerized Tomography (CT) features in Patients Under Investigation (PUI) for the disease would help in its management and containment .
Objectives: To describe the chest CT findings of PUI for COVID-19 pneumonia referred to the Department of Radiology of the Korle Bu Teaching Hospital; as well as to determine the relationship between symptom onset and severity of the chest CT findings .
Methods: The study was retrospective and included 63 PUI for COVID-19 referred to the Department between 11th April , 2020 and 10th June , 2020, for non-enhanced chest CT imaging . Clinical data were obtained from patients' records and Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) results were acquired after the CT evaluation .
Results: The mean age in years was 51.1±19.9 SD . More males (52.8 %) than females (47.2 %) tested positive for COVID-19 and the age range for positive cases was 7 months to 86 years, with a mean of 53.2±21 SD years . Common features of COVID-19 pneumonia were bilateral posterior basal consolidations, Ground Glass Opacities (GGO) and air bronchograms . Findings were worse in patients scanned 5-9 days after onset of symptoms . Conclusion: Adequate knowledge of chest CT features of COVID-19 pneumonia, proves a valuable resource in triaging of symptomatic patients and consequent containment of the disease in the hospital setting .
