Use of chest CT-scan images to differentiate between SARS-CoV-2 infection and fat embolism: A clinical case.

The authors present the case of a young man victim of a traffic accident during the SARS-CoV-2 confinement, having presented a fracture of the femoral shaft that was soon complicated by respiratory failure with oxygen desaturation. In this pandemic context, Covid-19 RT-PCR tests were carried out but returned negative. The CT images could suggest either a fatty embolism, a SARS-CoV-2 infection or both. The patient's condition improved significantly after going into intensive care and only symptomatic treatment. This case demonstrates the difficulty of differential interpretation of CT images between fatty embolism and SARS-CoV-2 infection.
