Pulmonary fat embolism remains a clinical diagnosis. A case study by Malagari et at. describes possible HRCT features of mild pulmonary fat embolism ¹. The predominate pattern is defined regions of ground glass opacities. Other patterns include centrilobular opacities and septal thickening ¹. Although these imaging patterns are non-specific when taken into clinical context can raise the possibility of fat embolism.
