“…Although the precise structure of the observed lesions was not taken into account in the study by Mader et al, the extent of opacities was correlated with several patient outcomes including Intensive Care Unit (ICU) length of stay (R = 0.81; p<.001) ( 14 ). Typical findings in COVID-19 include Ground Glass Opacities (GGO) which are often bilateral with a peripheral, posterior and basal distribution ( 15 , 16 ). Adjacent pleura thickening, interlobular septal thickening, and air bronchograms are also common, each occurring in approximately half of cases ( 16 ).…”

Background The novel coronavirus (COVID-19) has presented a significant and urgent threat to global health and there has been a need to identify prognostic factors in COVID-19 patients. The aim of this study was to determine whether chest CT characteristics had any prognostic value in patients with COVID-19. Methods A retrospective analysis of COVID-19 patients who underwent a chest CT-scan was performed in four medical centers. The prognostic value of chest CT results was assessed using a multivariable survival analysis with the Cox model. The characteristics included in the model were the degree of lung involvement, ground glass opacities, nodular consolidations, linear consolidations, a peripheral topography, a predominantly inferior lung involvement, pleural effusion, and crazy paving. The model was also adjusted on age, sex, and the center in which the patient was hospitalized. The primary endpoint was 30-day in-hospital mortality. A second model used a composite endpoint of admission to an intensive care unit or 30-day in-hospital mortality. Results A total of 515 patients with available follow-up information were included. Advanced age, a degree of pulmonary involvement ≥ 50% (Hazard Ratio 2.25 [95% Cl: 1.378 to 3.671], p= 0.001), nodular consolidations and pleural effusions were associated with lower 30-day in-hospital survival rates. An exploratory subgroup analysis showed a 60.6% mortality rate in patients over 75 with ≥ 50% lung involvement on a CT-scan. Conclusions Chest CT findings such as the percentage of pulmonary involvement ≥ 50%, pleural effusion and nodular consolidation were strongly associated with 30-day mortality in COVID-19 patients. CT examinations are essential for the assessment of severe COVID-19 patients and their results must be considered when making care management decisions.

The first case of coronavirus disease 2019 (COVID-19) was declared in December in Wuhan, before becoming a global pandemic in a few weeks. Several complications of this infection have been reported. However, a spontaneous pneumomediastinum has rarely been described. We report the fourth case of this extremely rare complication in a 65-year-old male patient with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pneumonia, discovered during his therapeutic management by a CT scan control.

Introduction: COVID-19 caused by SARSCov-2 could be serious and fatal. The objective was to determine the correlation of clinical, biological, CT and prognosis of severe COVID-19 according to the extent of lung lesions on the chest CT scan. Patients and method: This is a retrospective analytical study carried out in the department of pneumology University Hospital of the Joseph Raseta Befelatanana, Antananarivo, Madagascar for a three-month period from March to May 2021. Results: 78 severe COVID-19 cases met the inclusion criteria, for an incidence of 66.7%. The mean age of our patients was 52.81 ± 16.64 years. Age did not differ for the three CT extension groups (p = 0.60). Male gender, dyspnea, C-Reactive protein elevation correlated with the extent of lung damage (p <0.05). On CT scan, the ground glass image and bilateral involvement were also associated with CT extension of lung lesions (p = 0.03, p = 0.04). The prognosis in terms of mortality was worse in severe COVID-19 patients with disease greater than 26%. The overall death was 6.41%. Conclusion: Factors such as male gender, dyspnea, C-reactive protein, frosted glass and bilateral images of severe COVID-19 patients were correlated with the CT extent of lung lesions. Their understandings would make it possible to predict the unfavorable evolution of these lesions on a CT scan, thus reducing mortality.
