Abstract

Here, we present a case of fat embolism syndrome (FES) in which ultrasound sonography and computed tomography successfully visualized fat embolus in the femoral vein. A multimodality approach was particularly useful for early and specific diagnosis.

Keywords: bone fractures; fat embolism syndrome.
