Abstract
Background: Chest Computerized Tomography (CT) features of Corona Virus Disease 2019 (COVID-19) pneumonia are
nonspecific, variable and sensitive in detecting early lung disease. Hence its usefulness in triaging in resource-limited regions.
Objectives: To assess the pattern of chest CT scan findings of symptomatic COVID-19 patients confirmed by a positive RTPCR
in Ghana.
Methods: This study retrospectively reviewed chest CT images of 145 symptomatic RT-PCR positive COVID-19 patients
examined at the Radiology Department of the Korle Bu Teaching Hospital (KBTH) from 8th April to 30th November 2020.
Chi-Squared test was used to determine associations among variables. Statistical significance was specified at p≤0.05.
Results: Males represent 73(50.3%). The mean age was 54.15±18.09 years. The age range was 5 months-90 years. Consolidation
88(60.7%), ground glass opacities (GGO) 78(53.8%) and crazy paving 43(29.7%) were the most predominant features. These
features were most frequent in the elderly (≥65years). Posterobasal, peripheral and multilobe disease were found bilaterally. The
most common comorbidities were hypertension 72(49.7%) and diabetes mellitus 42(29.2%) which had significant association
with lobar involvement above 50%.
Conclusion: The most predominant Chest CT scan features of COVID-19 pneumonia were GGO, consolidation with air bronchograms,
crazy paving, and bilateral multilobe lung disease in peripheral and posterior basal distribution.
