BACKGROUND There is no study in the literature in which only chest CT findings of deceased cases obtained at admission were examined and the relationship between these findings and mortality was evaluated. Metod: In this retrospective study, a total of 117 deceased patients with COVID-19 infection confirmed by positive polymerase chain reaction and undergone chest CT were enrolled. We evaluated initial chest CT findings and the relationship of each, its location, prevalence and frequency with mortality. RESULTS The mean age of patients was 73 ±18 years, 71 of all patients were male and 46 were female.The predominant feature was pure GGO lesion (82.0%), and 59.8% of cases had pure consolidation. There was no cavitation, or architectural distorsion. Pericardial effusion was found in 9.4%, and pleural effusions were found in 15.3% of patients. Mediastinal lymphadenopathy was only 11.9% in total. CONCLUSION In deceased patients, on admission CTs, pure consolidation, pleural and pericardial effusion, mediastinal LAP were more common than ordinary cases. It was these findings that should also raise the concern when they were seen on chest CT, therefore, these radiologic features have the potential to represent prognostic imaging markers in patients with COVID-19 pneumonia.
