Abstract

Introduction: The pandemic disease COVID-19 has varied presentations clinically and even
radiologically. Early diagnosis and treatment help in containment of the disease. Therefore, assessing
the radiological patterns in order to contribute to the diagnosis COVID-19 is the aim of this study.
Materials and method: A cross-sectional descriptive study from January 2021 to June 2021 was
carried out on 165 patients suspected of COVID-19 with delayed RT-PCR report or in cases with initial
RT-PCR negative, but having high clinical of suspicion of COVID-19. HRCT pattern in such cases
were documented and correlated with the repeat RTPCR and other laboratory parameters such as
Interleukin IL-6, serum ferritin, C-reactive protein, Lactate Dehydrogenase.
Results: Most common HRCT pattern was bilateral multifocal peripheral ground glass opacities
predominantly involving posterior segments. Other common patterns were crazy paving and
consolidation.
Conclusion: Specific patterns on the HRCT can be used in diagnosis of COVID-19 when there is high
clinical likelihood, however the study should be used judiciously only when indicated.
