Imaging findings
CT reveals rib fractures on the left side and a hyperattenuating, oval-shaped hematoma. The medial aspect of this hematoma demonstrates fat, representing the displaced extrapleural subcostal fat sign.
Key takeaways
The displaced extrapleural fat sign, characterized by fat displaced internally by an extrapleural collection, is a highly useful indicator of an extrapleural hematoma, most commonly caused by trauma. It helps distinguish an extrapleural process from a parenchymal or pleural one.
